Laura: Hello and welcome to another episode of Lex Education, the science comedy podcast, where me, Laura Lex, tries to learn science from my real life brother, Ron.
Ron: Hello, I'm Ron.
Laura: That is Ron.
Laura: How are you doing, Ron?
Ron: I'm okay.
Ron: I'm very exhausted.
Laura: You've had a big week in your actual job job?
Ron: A big week in my actual job job.
Ron: And then you were in Brussels before that.
Ron: And then what they don't tell you about being an adult is a lot of doing jobs is drinking.
Ron: So it's been like seven days on the truck.
Ron: Yesterday, I accidentally ate three full English breakfast as well, so I've had to do a lot of digesting as well.
Laura: That doesn't sound like an accident.
Laura: That sounds amazing.
Ron: Well, we were in the hotel and I had a brilliant plan to get up in time for breakfast, eat a bunch and then go back to sleep, which was amazing.
Ron: Two plates of full English breakfast at this buffet.
Ron: And then we went to a cafe, and then Judith and our friend Ross put me on the spot ordering.
Ron: I panicked and ordered another thing called a mega breakfast about 3 hours later.
Ron: Yeah, that's what I'm going through.
Laura: It's one of the things I miss most now that I'm vegetarian, is full English breakfast.
Laura: Because if I'm going to eat meat, I like it to be really cruddy meat.
Laura: Like real cruddy.
Laura: I don't want a fine steak, I want a sausage that barely resembles but.
Ron: That'S more eco friendly.
Laura: You think?
Laura: Yeah, because it's waste products.
Laura: Practically dogfish.
Ron: It's all of the noses and buttholes and Grundles and stuff.
Ron: Like, it's not just the sort of the prime leg or the wing or whatever.
Laura: Yeah.
Laura: I still don't want to eat things at the moment.
Laura: We've got some thank yous to do, firstly, as always.
Laura: Thank you, podspike.
Laura: They're probably the reason you're listening to this, because they helped us choose a hosting site, which is where you put your podcast, and then it gets sucked into all the other places that a podcast can be.
Laura: That's right, isn't it?
Ron: Wrong.
Ron: Yeah.
Ron: And you might have seen, like, we were in the podcast of the week the other day.
Ron: No big deal.
Ron: But that's all.
Ron: Fod spike.
Laura: Yeah.
Laura: They wrote us press releases.
Laura: It's still us a little bit because we've made a nice podcast.
Laura: But also them.
Laura: It was them in a big way.
Laura: So thank you very much for podspike.
Laura: Also, we've got a massive thank you to Carol, who's made us a scrabble tableau.
Ron: Scrablo?
Laura: Yes, a scrablo.
Laura: So Carol has made us a framed art installation.
Laura: We'll put it on the Instagram.
Laura: But thank you so much, Carol.
Laura: It's our first fan art.
Laura: Ron, it is your first ever.
Ron: I've never had a thing made for me before and it's just dismissed.
Ron: It's my catchphrase.
Ron: It's basically all me.
Laura: Yeah.
Laura: Well, thank you so much, Carol.
Laura: We love it.
Laura: And we will pop it on the instagram this week.
Laura: Paisley Buddy has also on Twitter, has sent us a very cool interactive periodic table, which I'll put a link to it in the show description.
Laura: Thank you for showing us that, Paisley Buddy.
Ron: A big well done to Jenny, for being the person with the even less accessible definition of a metre.
Laura: Last week, I said a metre was about a wheelbarrow and Ron laughed a lot.
Laura: So we asked you on social media, how do you picture of roughly a metre?
Laura: And we got some interesting responses back.
Laura: Quite a lot of people just said what you said, Ron do.
Laura: They just picked it a metre ruler.
Ron: Yeah.
Ron: Including your husband paragon of sensibility.
Laura: No, he married me.
Laura: How can you possibly call him that?
Laura: Jenny offered us a buzzard's wing span.
Ron: Nonsense.
Ron: That doesn't help.
Laura: No.
Laura: You're going to choose that over a wheelbarrow?
Laura: You're full.
Ron: How many bars can you fit in a wheelbarrow?
Ron: Question.
Laura: Depends how argumentative they are about it.
Laura: A large step.
Laura: That's crazy, because one of Tom's large steps is way different to one of mine.
Ron: Yes, but I think that was Kevin, wasn't it?
Laura: I believe so.
Ron: If he's picturing one of Tom's largest steps instead of his own, then yes, he is mad.
Ron: But I presume he's imagining his own legs and body.
Laura: And also a guitar.
Laura: That was another option.
Laura: But I think a guitar is longer than a metre.
Ron: You think a guitar is bigger than a wheelbarrow?
Laura: Yeah.
Ron: That's the problem with this system.
Laura: Size is subjective.
Laura: So we've also had some brilliant puns.
Laura: Keep them coming.
Laura: We're enjoying those.
Ron: No, they need to stop.
Laura: What?
Laura: Why?
Ron: Can't be better at this than us.
Laura: Oh, they have to be.
Laura: Somebody has to be.
Laura: Ron, I'm going to delete your comment there in the show notes where you said, this needs to stop.
Laura: It's not keep them coming.
Laura: So let's jump into the episode now.
Laura: This is probably my favourite episode we've released yet.
Laura: I think this is the episode where the wheels really start to come off down in a big way.
Laura: We're going back to physics.
Laura: Yeah, maybe.
Laura: How many times you hear the word down in this episode?
Laura: And let's listen to Laura and Ron start to fall out.
Laura: Listen, Ron, how are you doing?
Laura: Because I'm tired and very grumpy and I'm just not in the mood for your s*** today.
Laura: I feel like this is just going to be a really angry episode.
Ron: This episode, I think, might really get you back up as well.
Laura: It's already up, though.
Laura: What was the last physics?
Laura: What was physics again?
Laura: Which one was that?
Laura: It's not atoms, is it?
Ron: No.
Ron: So that was my first question.
Laura: Stupid woman with the ball.
Ron: Yeah.
Ron: Can you remember what force is and what it's measured in?
Laura: Force is like it's force, isn't it?
Laura: You know what force is that?
Laura: I think it's measured in Newton's.
Ron: It is measured in Newton's.
Ron: Okay.
Ron: Why don't you try and not necessarily define forces in the vague concept of that, but what?
Laura: A force is like moving stuff or force?
Laura: I don't know another word for force.
Laura: This isn't thesaurus education.
Laura: I don't know, Ron.
Laura: I think it's just force.
Laura: It's just like what is doing a thing?
Laura: Oh, that is it.
Laura: It's for that?
Laura: Is that it?
Laura: I hate this.
Ron: All right, talk to me about a four day question.
Laura: Don't just rephrase the question in a different patronising way.
Laura: I just did that.
Laura: I just did talk to you about force.
Laura: I said it.
Ron: I'm asking a different question.
Ron: Imagine you are the woman throwing the ball.
Laura: I'm tired.
Laura: My arms tired.
Ron: What force could you apply to it?
Laura: What do you mean?
Laura: I could get, like, my arm.
Ron: The.
Laura: Ball, I'm throwing it with force.
Laura: I don't know what you're asking me for, Ron.
Laura: I don't know what the question is.
Laura: I'm going to throw the ball with my arm forcefully.
Laura: I throw it hard.
Laura: Is that it moved my arm fast.
Laura: Fast arm hysterical already.
Laura: I hate you.
Laura: And I don't know is this what we did last time?
Ron: So the first thing to know is what a resultant force is.
Laura: Moving?
Ron: No, I'm going to teach you this.
Ron: This isn't a guess thing.
Ron: Okay.
Ron: So basically, all of the forces that act upon an object can be distilled into one force, and that is the resultant force.
Ron: Okay.
Ron: So let's think about a Blue Planet plastic water bottle that says Spa Rain on it, sitting on a table.
Ron: What force on it?
Ron: Blue plastic bottle that says Spa Rain, I think.
Ron: No, that's just what I'm looking at.
Ron: Now, imagine that on a table.
Laura: Yeah.
Ron: What forces do you think are being applied to that bottle?
Laura: Like someone might want to drink from it.
Laura: What do you mean?
Laura: Gravity?
Ron: Yes.
Ron: So gravity is, in effect, pulling it down onto the table.
Laura: Yeah.
Ron: So what other force can you think because gravity is pulling it down, but the bottle is not moving?
Laura: No.
Laura: Because it's on the table.
Ron: Yeah.
Ron: So the table is effectively pushing up against gravity.
Laura: No, it isn't.
Laura: The table still.
Ron: But it's applying a force to the bottle.
Laura: No, I think it's just there.
Ron: But it is.
Laura: It's not, though, is it?
Laura: Because it's just a table.
Ron: Yeah, but it's applying a force to the bottle that counteracts the force of gravity.
Laura: No, it isn't.
Laura: It's just there in the way.
Ron: You're going to have to go with me on this.
Laura: No, I think science needs to go with me, that they are just f****** making things up to give themselves a job.
Ron: But then why wouldn't the bottle be moving if there was nothing?
Laura: The table is in the way.
Laura: I'm not saying the table is not stopping it.
Laura: It is, but it's not pushing up.
Laura: It's just there a static table.
Ron: But you agree that gravity is pulling down?
Laura: Yes.
Ron: So surely then you must agree that the table is counteracting that the table.
Laura: Is harder than the bottle.
Ron: Yes.
Ron: You must see that the table is equal and opposite to gravity because the bottle is not moving.
Ron: Yeah, and what's the opposite of pulling?
Laura: Stopping.
Ron: Don't be like that.
Laura: Why does it have to be the opposite?
Laura: It's not the opposite, it's just in the way.
Ron: Because gravity is pulling.
Laura: Yeah.
Ron: That needs to be counteracted.
Laura: No, it doesn't.
Laura: Not if you just stop it.
Ron: Yes.
Laura: I don't understand why it's got to be the opposite.
Ron: Because what do you think is stopping?
Laura: Crisps?
Laura: It doesn't mean I've stopped because I've started throwing up crisps.
Laura: It just means I'm not eating crisps anymore.
Laura: Why can't the table just be doing that?
Ron: Okay, imagine it's not a table, it's your hand.
Ron: You're holding the bottle.
Laura: Yeah.
Ron: Okay, and then what happens if someone, like, if you're holding something heavy and then someone takes that away from you and you don't really realise I said.
Laura: Thank you so much for taking no.
Ron: Your arms kind of, like, move upwards, don't they?
Laura: No, I'm not a cartoon character.
Ron: Yes, they f****** do.
Laura: But if my hand was lying on the floor and someone took something heavy off it, my hand wouldn't ping into the air.
Ron: No, because the floor is applying the force in that scenario.
Ron: But you see what I mean?
Ron: Like, if you were holding something I.
Laura: Don'T see what you mean in the slightest.
Laura: Otherwise, all the floor, like when I took things off the table, the table will be pinging up like a jelly table.
Ron: Why would it be?
Laura: Because you're saying it's pushing.
Laura: So then when it stopped pushing, it would be pinging up when you took the weight off it.
Laura: Mackie agrees with me.
Ron: But you see what I mean with the arm thing, right?
Laura: No, not in the slide, just.
Ron: Yeah, but you do because.
Laura: You can't just keep telling me I do understand.
Laura: I don't.
Laura: Ron, you're talking cobbledygook.
Laura: A table isn't pushing.
Ron: It is.
Ron: But why would it be different with your arm and a table?
Laura: You're the one that thinks my arm is made of jelly.
Ron: I never said a bean about jelly.
Ron: Right, but you understand that to hold something in the air, you're applying a force.
Ron: God, I honestly even on to the topic that was in the syllabus.
Ron: I'm trying to lay the f****** groundwork for that.
Laura: Right, okay.
Laura: My table, my desk is pushing my laptop up to the sky.
Laura: Fine, you win.
Ron: Not up to the sky, Laura.
Ron: It's just counteracting the force of gravity.
Ron: You know, that one of Newton's laws of thermodynamics for every reaction, there's an equal and opposite reaction.
Laura: So he thinks fine.
Ron: Okay, right.
Ron: Let me try to think of another.
Laura: Way to explain I don't care, Ron.
Laura: The table's pushing.
Laura: Fine.
Laura: If that's what you say, I believe you.
Ron: This is the whole thing.
Laura: Well, there we go.
Laura: I've learned it now what?
Laura: I mean.
Laura: Let's do another bit now.
Ron: We're moving on to resultant forces.
Ron: Resultant forces.
Ron: So basically what it is, is that all of the forces that act upon an object can be distilled into one force, like kind of averaged out.
Ron: But it's quite hard to explain that to you if you're going to deny a large proportion of the forces that are acting upon a thing.
Laura: No, not denying anything.
Laura: My table is pushing.
Ron: So I thought maybe it would be fun if you had a couple of situations and you told me what the resultant forces were in these situations.
Laura: I can't wait.
Laura: That does sound fun.
Laura: You're right.
Ron: Listen up, lord.
Ron: You need to stop being an art.
Laura: I said I do it.
Laura: I said it sounded fun.
Laura: Stop being rude.
Ron: Okay, could you try and tell me the resultant force when a ball rolls down a hill?
Laura: Down.
Laura: Moving downward motion.
Laura: What are you saying?
Ron: So let's think about all of the forces that are acting upon this ball, right.
Laura: Down.
Laura: Downness, yes.
Ron: So it's got gravity working against it.
Ron: What else?
Ron: Gravity is pulling it down.
Laura: Down, yeah.
Laura: The wind.
Ron: Yeah.
Ron: A bit of air resistance, friction.
Ron: That's kind of applying a force in the other direction, slowing it down.
Laura: I hit a pebble.
Ron: It's a smooth, flat.
Laura: Heat energy.
Laura: It's going down the hill.
Laura: Somebody through it.
Ron: Here's what we're going to do.
Laura: Kinetic energy.
Laura: Shut up.
Ron: Draw a diagonal line yes, sir.
Ron: Across on your page.
Ron: And then draw a ball on it.
Laura: Yes, I've done that.
Laura: Two points.
Ron: Okay, now we're going to draw arrows to represent the different forces that are being applied to this ball.
Ron: Okay?
Laura: Yeah.
Ron: So draw an arrow going from the ball pointing down, like down or down the slope.
Ron: Well, which way would gravity be pulling it?
Laura: To the core of the Earth.
Laura: No, not the Moon.
Laura: To the core of the Earth?
Ron: Yes.
Laura: What's the Moon doing?
Laura: Pulling us all to the sea?
Ron: In this world, there's no Moon.
Ron: We will cover the Moon in, like, eight years.
Laura: Okay, so down to the middle of the Earth.
Ron: Yes.
Ron: So on your diagram, what direction is that?
Laura: Down to the floor.
Laura: Down to the bottom of my page?
Ron: Yeah.
Ron: Just straight down?
Laura: Yeah.
Ron: So draw an arrow pointing straight down.
Ron: Maybe mark it with a G.
Ron: So we know that that's gravity.
Laura: That is gravity.
Ron: Then the next one you mentioned is wind.
Ron: Let's just roll that all into friction, because obviously the surface of the hill is going to be applying some friction as well.
Ron: Yeah.
Laura: Are you imagining the wind is blowing into the ball or from behind the ball?
Laura: Because I'm imagining the wind is blowing the ball down the hill.
Ron: There's no wind.
Ron: No, I said we're going to wrap that up into friction.
Ron: Okay, so there's no wind, there's just air resistance and friction.
Laura: Okay.
Ron: What would these things do to the ball?
Laura: Slow it down.
Ron: So they are applying a force going in which direction?
Laura: No, direction.
Laura: Stop.
Laura: Direction.
Laura: Direction.
Ron: No.
Laura: Stopping.
Laura: Stopped.
Laura: Slow down.
Laura: What are you wanting?
Laura: Stop.
Ron: Stop.
Ron: Not at direction.
Laura: I know, but it's not going the ground isn't saying, Go this way.
Laura: The ground is just saying, don't do it, please, isn't it?
Ron: Yes, but it is supplying a force in a direction that is up, kind of up.
Ron: The friction would be, I think, applying a force just going up the hill because it's slowing it down.
Ron: It's trying to stop it from rolling down the hill.
Laura: Friction.
Laura: Oops, I've written friction.
Ron: In your mind.
Ron: What?
Ron: Which direction on your hill would the ball be?
Laura: Moving down the hill.
Ron: Okay.
Ron: But the two force arrows that we've drawn on it so far, they wouldn't really make it move that way, right?
Ron: No, because they'd be making it move sort of down and a bit backwards.
Laura: Yeah.
Ron: So there must be some other forces being applied to the ball.
Ron: Could you hang on a guess at any of them?
Laura: I don't know all the fancy words for them, but it's down, isn't it?
Laura: It's going down the hill.
Laura: Did somebody throw the ball?
Ron: No.
Ron: We are just thinking about a theoretical ball that is Midwest.
Laura: Do you remember the advert where all the colourful bouncy balls go down the street in San Francisco?
Ron: Yeah.
Ron: With Josie Gonzalez.
Ron: Playing good, advert.
Ron: Stop thinking about that.
Ron: We're thinking about a theoretical for me.
Laura: To think of a hill, I think of San Francisco.
Ron: That's just lovely.
Laura: Do you know what for directed in San Francisco?
Laura: Princess Diaries.
Ron: Yes.
Ron: So we're thinking about a theoretical ball that is in the process of rolling down a hill.
Laura: Yes.
Ron: There is no story before or after that.
Laura: Okay.
Laura: So what do you want me to say?
Laura: Down.
Ron: I'm working upon this ball.
Laura: Well, down and the friction one.
Laura: Oh, I see what you mean.
Laura: Because the floor is being the table.
Ron: Yes.
Laura: Unless it was like a really heavy ball, it couldn't burrow through the floor.
Ron: Exactly.
Laura: So the floor is the table.
Laura: It's going up.
Ron: Well, which direction, do you think?
Ron: Straight up?
Laura: Yeah.
Laura: Well, no, probably at the same angle as the floor is.
Ron: Yes.
Ron: Perpendicular to the floor.
Ron: Very good.
Laura: What's that called?
Laura: Table?
Ron: Well, that's the force of the hill pushing upwards against the ball.
Ron: But I didn't really want to go down that nasty avenue again, pushing.
Laura: Okay.
Laura: I've drawn that arrow.
Ron: Okay.
Ron: So those are the three forces acting upon the ball.
Laura: So how are we going forwards?
Ron: Can you a picture of your diagram just so I could double cheque?
Laura: Just find out all the things I've done wrong in it.
Ron: Yes, but that's kind of the point.
Ron: If you could set that to me and then I can just double cheque that you got it right.
Ron: And then we can talk about the resultant force.
Ron: Okay, sure.
Ron: Yeah.
Ron: Okay.
Ron: Usually you do them with the arrows coming out of the ball, but all of the arrows are correct.
Ron: Cool.
Ron: So the resultant force is kind of the average of those three.
Ron: So you can imagine that the friction on the ball is quite low, right?
Laura: Yeah.
Laura: Because it's on the floor.
Ron: Yeah.
Ron: And it's rolling.
Ron: It's not skidding down the hill.
Ron: It's a ball.
Ron: It's rolling like it was a rubber trying to sled down a sandpaper hill.
Ron: Then the friction is going to be just enormous.
Ron: But it's not that.
Ron: That would be mad.
Ron: It's a ball.
Laura: That would be crazy.
Laura: Scientists would never do that.
Laura: Can you imagine the chaos?
Ron: Yeah, it might be easier for you to.
Ron: At least the way that my brain works.
Ron: Is it's easier to picture it if the arrows come out of the ball?
Laura: Why?
Ron: Oh, God, mackie just made a horrible noise.
Laura: Yeah, she's come over to Cheque I'm okay because I was shouting a lot.
Ron: I don't know.
Ron: Just give it a go with that and see if you can because I think it's easier to picture when the arrows are coming out, where the sort of the average of them all is.
Ron: Make gravity the biggest one, then the hill one a little bit smaller than the gravity one, and then make the friction one quite small.
Laura: Start in the ball, though.
Laura: Going up into the sky.
Ron: No, coming out of the ball and going down for gravity.
Ron: Coming out of the ball and going up for the hill one.
Laura: Yeah, well, that's not right though, because it's not the ball trying to fly up, is it?
Ron: We're just talking about things so stupid.
Ron: Okay.
Laura: I like my dog, Ron.
Laura: She's real.
Ron: So now it looks like a clock a bit.
Ron: So can you see now that you've got the hill force kind of pushing a bit to the left and then the gravity force coming down and then a little bit of friction?
Ron: What do you think the resultant force from that would be?
Laura: I'm scared to say it, Ron.
Ron: No, just give it a go.
Ron: I'm not going to be mean about it.
Ron: Down, straight down.
Laura: Down the hill.
Ron: Closer.
Ron: Yes.
Ron: Yeah, we'll go a bit down the hill, put it to the left.
Laura: Yeah, I know what a f****** ball does.
Laura: I just don't believe your claims that it's only happening because the hill is pushing it.
Ron: Why else would it be happening?
Laura: Then somebody threw it.
Laura: If a whole hill was pushing a tiny ball, it would know about it.
Ron: It does because it stays on the top of the hill.
Laura: Yeah, but that's just because the hill is made of tarmac.
Ron: It sounds like a horrible hill, but that hill is pushing.
Laura: I don't think it's pushing though, is it?
Laura: It's just there.
Laura: It's just not allowing it self to be pushed.
Laura: It's not pushing.
Laura: It's just not being pushed, you know?
Ron: No, I don't know.
Ron: It's not correct.
Ron: So the next one that we're talking about is Newton.
Laura: Is that who I've got to talk to?
Ron: I mean, the entire physics community, I think.
Laura: Okay.
Ron: Right.
Ron: Here's the next one.
Ron: A pendulum.
Ron: What forces do you think are acting upon the pendulum?
Laura: Gravity.
Ron: Yes.
Laura: Is there no wind again?
Ron: Yeah, no wind.
Laura: That's it then.
Laura: Just gravity.
Ron: So what's the pendulum doing?
Laura: Just hanging?
Ron: No, I said a pendulum swinging before, I think.
Laura: What swinging then?
Ron: Yeah, but the only force working on it is gravity.
Laura: Yeah.
Ron: What do you think it would be doing if actually, in reality, for a second, the only thing acting upon it would be gravity?
Laura: It would be falling to the centre of the Earth.
Ron: But it's not doing that because of the moon.
Ron: Bounce the moon out your life, mate.
Ron: It's not factoring in.
Ron: Okay, so the ball is not plummeting to the centre of the Earth?
Laura: Yes.
Laura: Because it's on a hill.
Ron: It's not from a hill.
Ron: It's a pendulum.
Laura: Well, why did you say the ball then?
Ron: It's a ball on a pendulum.
Ron: It's a pendulum.
Ron: Okay.
Ron: It's a clock pendulum.
Ron: The pendulum is not plummeting to the centre of the earth?
Laura: No.
Laura: Someone's holding it.
Ron: Let's say that.
Ron: Yeah.
Ron: Okay.
Ron: Someone's holding it.
Ron: Why would someone be holding a pendulum?
Ron: That doesn't make any sense.
Laura: They're hypnotising someone else.
Ron: So it's not on a clock.
Ron: Are you imagining, like, a pocket watch on a okay, I thought you meant like a pendulum inside a grandfather clock.
Laura: That's what I was picturing.
Laura: Someone's holding one of those hypnotising someone.
Ron: Someone's holding a pendulum from a few talking.
Laura: That's what jumped into my head when you said a pendulum.
Ron: Why?
Laura: I don't know.
Laura: I just thought, oh, swinging.
Laura: Wait a minute.
Laura: Newton's cradle.
Ron: Yeah.
Ron: Those are pendulums.
Laura: Yeah.
Laura: And Newton, he's the man we're talking about.
Ron: We're talking about a pendulum.
Laura: Yeah.
Laura: All right.
Laura: What do you want me to do?
Laura: Pin the pendulum to something.
Ron: Right.
Ron: Let's not have it be a weird person holding a part of a grandfather clock because that is honestly insane.
Ron: Let's think of it as just let's still have someone hypnotise someone.
Ron: Let's do it the normal way.
Ron: With a pocket watch on a string.
Ron: Okay?
Laura: Yeah.
Speaker UNK: Okay.
Ron: And now we're thinking about that when it is at the middle of its swing.
Ron: So it's right at the bottom.
Laura: Yeah.
Ron: Okay, so we've identified gravity is pulling on the pocket watch.
Laura: Yeah.
Ron: But the watch is not plummeting to the centre of the earth.
Laura: No.
Ron: So what other forces are working upon it?
Laura: Well, the magician's hand is pulling it.
Ron: Yes.
Ron: And that's attached by the chain.
Ron: Right.
Laura: You're thinking about it on a chain.
Ron: Yeah.
Ron: What would you think about it on?
Laura: Just a long metal stick.
Laura: Like a rod.
Ron: What fears?
Ron: I thought this was just something really pervasive in pop culture.
Laura: What are you typing about?
Laura: Who are you telling?
Ron: I'm not telling anyone.
Ron: I'm trying to find a picture of a magician hypnotising someone with a boggy watch to see if I'm losing my f****** mind.
Laura: Well, if it was a pocket watch.
Laura: I don't know, maybe a ribbon.
Ron: It's okay.
Ron: It seems like every image on Google backs me up.
Ron: That it would be on a chain.
Ron: That's fine.
Ron: We're talking about the pendulum when it's at the bottom of its swing.
Ron: Okay.
Laura: Yeah.
Ron: So gravity is pulling it down.
Ron: The tension in the chain is pulling it up.
Laura: Yeah.
Laura: Thing is, because of the way I've drawn my pendulum, it's hard for me to draw an arrow going up, coming off the pendulum.
Laura: It just looks like the whole pendulum is an arrow, but you could just.
Ron: Use the point on the arrow to kind of denote how far up that the force is, if you see why me?
Laura: Sure.
Ron: So when the pendulum is at the bottom of its swing, it is neither moving up nor down.
Ron: Yes.
Laura: Just like the grand or Duke of York.
Ron: Going to take that as a yes.
Ron: I didn't get the reference.
Laura: And when they were down, they were down, and when they were only halfway up, they were neither up nor down.
Laura: That song, you know that.
Ron: Okay, sure.
Laura: Oh, the grand old Duke of York, he had him there.
Laura: No.
Laura: What's the tune?
Laura: At the beginning of it, he marched them up to the top of the hill and he watched them down again.
Laura: That's not quite right, though, is it?
Ron: I'm going to send you down.
Ron: We are six lines into my research.
Laura: Yeah.
Laura: We've only got ten more minutes.
Ron: Yeah.
Ron: We're just going to get through these results and force bits, and then we're going to have because after this, I was about to introduce a new concept to you called work.
Ron: I haven't got enough grey hairs already.
Laura: I'm working really hard.
Ron: So do you agree that at the bottom of it swing, the pendulum is not moving up nor down?
Laura: Yes, I said that.
Ron: You just started talking about Prince Andrew or something.
Laura: No.
Laura: Yeah.
Laura: He was Duke of York, actually, wasn't he open?
Ron: Yeah, he was.
Ron: It was a good joke.
Laura: Yeah, I said that.
Laura: Yeah.
Ron: So the tension in the chain and the gravitational force put it down equal.
Ron: Okay.
Laura: At that point, yes.
Ron: At that point, yes.
Ron: When it keeps on swinging, they then wouldn't be equal.
Ron: No, of course not.
Ron: Because then it would start moving up or down.
Laura: And then it would be up or.
Ron: Down at the bottom of its swing.
Laura: Yes.
Ron: Is the pendulum moving?
Laura: No.
Ron: Yes, it is.
Ron: Yes, it is moving.
Ron: What force do you think is making it move at that point?
Laura: Is it just a choice of these two forces?
Ron: No.
Laura: Momentum, force.
Ron: Yes.
Laura: Pulled that out of my b*******.
Ron: Well done.
Ron: Yes.
Ron: The momentum is moving it.
Ron: So what do you think the resultant force, when you take into account those three things, what does that look like.
Laura: Swinging.
Ron: In terms of an arrow?
Laura: Like a big smiley face, curly side, left and right, diagonal.
Ron: Please don't just say things.
Laura: I don't like silence, though.
Laura: I like to fill it up, just.
Ron: Have a bit of a think about it.
Laura: What do you mean?
Laura: I've drawn an arrow.
Laura: It's got a bend in it halfway along.
Ron: Forces have to act in a direction.
Ron: They can't have bends in them.
Ron: The tension from the chain and the gravity.
Ron: One's pulling up, one's pulling down.
Ron: And then you've got the momentum, let's say going to the left.
Laura: Yeah.
Ron: Okay.
Ron: What do you think the average of those three forces is?
Ron: That leads leaves us with the resultant force?
Laura: A bit of left, a bit up, a bit down.
Laura: It's all of them, isn't it, on a pendulum?
Laura: I don't understand.
Laura: Some of each, they just take it in turns.
Laura: On a pendulum, they all have a go.
Ron: But we agreed just now we agreed.
Ron: You agreed with me.
Laura: I'm not trying to argue with you, but a pendulum just swings all around.
Laura: So I can't do one arrow to represent everything a pendulum is getting up to?
Ron: Yes, you can.
Laura: Not a straight one.
Ron: Yes, because we're talking about the pendulum at this specific point.
Laura: It's going stop, isn't it?
Ron: No.
Ron: Who.
Ron: It hasn't.
Ron: Right, so we agreed that stop saying we agree.
Ron: But we did f****** agree, so don't backpedal now.
Ron: Don't want to be known as a deal world trip.
Ron: I'm not at the bottom of its swing.
Ron: The ball is not moving up nor down.
Ron: Correct.
Ron: It's just moving sideways.
Laura: I found some wires sticking out of my wall.
Laura: What did you say?
Laura: Sorry?
Laura: The pendulum was what at the bottom?
Laura: It's down at the bottom of the hill?
Ron: Yes, it's at the bottom of its swing.
Ron: So at this point, it's not moving up or down because the tension in the chain and the gravity pulling it down at that moment are equal and opposite.
Ron: Right.
Ron: So when we're talking about resultant forces, what are they going to do?
Ron: Okay, think about it this way.
Ron: What if one of them was so maybe if we put it into numbers, it would make more sense.
Ron: Right.
Ron: So let's say that the gravitational force pulling it down is ten newtons pulling directly down.
Ron: The tension in the chain is pulling up ten newtons as well.
Laura: Yeah, it stopped.
Laura: I've already said that.
Ron: So they cancel each other out, right?
Laura: Yeah.
Ron: So if those two cancel each other out, what is the result?
Laura: In force stopping.
Ron: But it's not f****** stopped, has it?
Ron: Because it's still moving.
Laura: Well, then, why?
Laura: Because of the momentum.
Ron: The other one.
Ron: That's all I wanted you to say.
Laura: You can tell me to think about that one.
Ron: I told you to think about all of them.
Laura: Is this going to go left, then?
Laura: Really, isn't it?
Ron: Yeah.
Laura: Why can't you just tell me that to begin with?
Ron: Because f****** 14 year olds.
Laura: They'Re not doing anything else, are they?
Laura: 14 year olds aren't trying to pay the mortgage and drive places and find out what Ad blue means and where.
Laura: To put it in their car.
Laura: If anybody knows, can you please let me know?
Laura: Because it's been flashing for ages and I don't know what to do.
Laura: So of course they've got time to learn this s***, whereas I'm busy.
Ron: So we're going to do one more at the end.
Laura: No, I'm finished now.
Laura: I'm bored and it's stupid and I hate it.
Ron: Christ.
Laura: That was dog s***.
Laura: Physics is the worst one.
Laura: Sorry, Ron.
Ron: Sorry.
Laura: It's not right.
Laura: So it's really hard to learn because the hill isn't pushing and the pendulum isn't going left, it's going up and left and back down.
Laura: Okay, we'll see in a bit for the quiz.
Ron: Yeah.
Ron: So there's only two points on offer.
Laura: Okay.
Ron: Because to be honest, I couldn't face and there was so little content in the last episode that there was nothing else for me to make questions out of.
Laura: I bought myself three weeks, though, to get on board with this idea that a hill is cuddling a ball.
Ron: For one person?
Laura: No, the opposite.
Laura: Pushing a ball away.
Ron: Yes.
Ron: Laura, what is a resultant force?
Laura: The stuff that ends up happening.
Laura: The thing that happens.
Ron: Give me more like.
Laura: A ball is on a hill and gravity is pulling the hill into the floor and the hill is pushing the ball into the sky and friction is there and the ball rolls down the hill.
Ron: But what is the resultant force?
Ron: A couple of two things about the ball.
Ron: What is the resultant force?
Laura: I know that you keep repeating that question and looking at me, like, really intently.
Ron: What is a resultant force?
Ron: You can work it out from the name of it.
Laura: That's why I said It's the thing that's happening, the result.
Ron: That's not what you said.
Laura: I did.
Laura: I said, the thing that happens.
Ron: I don't think I can give this to you.
Laura: Why not?
Laura: You know that I know what I am.
Laura: I said, It's the thing that ends up happening.
Ron: Look, Laura, I'd love to give you the point.
Laura: No, you wouldn't.
Laura: Look at your stupid face smirking away.
Laura: This isn't how you give me the point, then.
Ron: It's not how school works.
Laura: We're not in school.
Ron: You don't get points for knowing stuff.
Ron: You get points for parroting back the thing that they want you to say.
Laura: And I did.
Laura: I said, It's the thing that ends up happening.
Laura: Yeah, but that's further away.
Laura: How is that further away?
Laura: It's a result.
Ron: All of the forces that act upon an object can be displayed as one resultant force.
Ron: It's when you match them all together, you average them all out.
Ron: What force is left at the end?
Laura: Yeah.
Ron: That is not the same as the thing that ends up happening.
Ron: Because in the example that you gave a ball rolling down a hill, the thing that ends up happening is the ball rolling down the hill.
Ron: The resultant force is like a diagonal line pointing downwards.
Laura: Yeah, that's because there's more down than there is hill push?
Laura: Yeah, there's a little bit of hill push.
Ron: I'll give you half a mark.
Laura: Give me the whole down mark.
Ron: Absolutely not.
Ron: Half a mark.
Ron: Are you ready for question number two?
Laura: Who can ever tell?
Ron: A small porcelain dog is sat on a large oak table.
Ron: What is the resultant force acting upon the dog?
Laura: The oak table is pushing the dog up and gravity is pulling it down.
Laura: The resultant force is that the dog is not floating in the air.
Ron: Close.
Ron: Try again.
Laura: The resultant force is that the dog is on the log.
Laura: Was it a log?
Ron: What?
Ron: Was it a large oak table.
Laura: A large oak table.
Laura: The dog is just on the large oak table.
Laura: It's just on it?
Ron: Yes.
Ron: So what's the resultant force?
Laura: Down.
Laura: Stop.
Laura: Stoppage?
Laura: Yeah.
Ron: There isn't one.
Laura: Stillness.
Ron: There isn't one.
Laura: I hate you when you do these trickos.
Laura: It's not fair, do you know that?
Laura: It confuses me as much as it is without doing trick questions.
Ron: I just thought, because we literally talked about this last week, you might have.
Laura: Got it, you know that I hang out my headphones during this and I walk away so angrily that I then sort of, like, obtusely forget everything we've done, but cancels it.
Ron: Cancels out.
Ron: The force of gravity is the force of the table.
Ron: They just cancel each other out.
Ron: Nothing happens to the top.
Laura: Yeah.
Ron: Which I'll give you another half a month for.
Ron: Stop.
Laura: I didn't say stop.
Laura: I said it doesn't stop it.
Ron: First you said down, so I think I'm being a bit lenient, to be honest.
Laura: Are you done?
Ron: Yeah.
Ron: That's the quiz.
Laura: That's it.
Laura: It's got physics garbage and I hate it.
Ron: Tell us at home how you did.
Ron: Did you get the full two points?
Laura: Did you say exactly the words that Mutant Ron needed you to say?
Ron: Did you answer the question?
Laura: I answered the question.
Ron: You make impassioned noises to kind of indicate you know what I'm talking about.
Laura: My science is bullshit because I know that a dog sat on a table doesn't, like, fall through the table and stuff, and I know how a ball goes down a hill, but if I don't say exactly the right type of down, I don't get the point for it, and that is stupid.
Ron: So are you asking for these lessons to be just like, what happens if you put a ball on a hill and then A, for me to clap when you say it rolls down, and B, for anyone to listen to them?
Laura: No.
Laura: We could have a chat about we could make it more like my degree was and then we have a chat about how the ball might be feeling as it goes down the hill.
Ron: Yeah.
Ron: How it was feeling in the context of the time that it rolled down.
Laura: How the witnesses looking at the ball rolling down might perceive the balls rolling in a different way.
Ron: Sure.
Ron: How it might be different if the Basalo man pushed it down a hill in gangland Chicago.
Ron: Something like that.
Laura: Yeah.
Laura: You know, useful stuff.
Laura: So that was a slog.
Ron: Yes.
Ron: Listening back.
Ron: More of a slog than I remember.
Laura: Yes, more of a slog for me, too.
Laura: And what's really sad is I've now recorded that with you.
Laura: I've edited it once, I've edited it twice for the second draught and I've listened back to it there and I still don't believe.
Ron: And now, on top of all of this, we're putting it out into the general public.
Laura: Do you know what, though?
Laura: I just have in the back of my head, though, when I was explaining this to dad and he went, well, it's not pushing.
Laura: And I was like, yes, dad agrees with me.
Laura: So we would normally ask you, how did you get on?
Laura: In the quiz, there were only two questions.
Laura: So I got 50% of the marks available, which is higher than a lot of my scores, so I'm fine with that.
Laura: Although getting half of each two points is a hard way to get 50%.
Laura: So there we go.
Laura: Let us know what you think.
Laura: What feedback do you have from us?
Laura: You can contact us on Lex education on all platforms TikTok, Instagram, Facebook and Twitter.
Laura: We're also on YouTube and the transcripts are available on our blog spot.
Laura: If you want to read along, you can email us, lexeducation@gmail.com, if you've got something to say that you don't want to be in the general public.
Laura: But bear in mind, we'll probably read it out here, so it will come around.
Laura: Our big question of the week is going to have to be if someone asks you to picture a pendulum, what do you picture?
Ron: Absolute batch it.
Ron: You are picturing a Rod mad.
Ron: Everyone please get in touch and let me know how right I am.
Laura: So there we go.
Laura: We'll be back to biology next week.
Laura: Thank goodness biology is fast becoming like a floating piece of driftwood in a sea of anarchy.
Laura: But we hope you've enjoyed physics too, and we will see you next week.
Ron: Class dismissed.
Laura: You got to say it in your voice.
Ron: Class dismissed.
Laura: Oh, my door slam.
Laura: Just as you said it.
Laura: It was so authoritative.
Laura: Do one more.
Ron: Class dismissed.
Laura: You sound like a ghost.
Ron: First.
Ron: Hello, I'm Ron.
Laura: That is Ron.
Laura: How are you doing, Ron?
Ron: I'm okay.
Ron: I'm very exhausted.
Laura: You've had a big week in your actual job job?
Ron: A big week in my actual job job.
Ron: And then you were in Brussels before that.
Ron: And then what they don't tell you about being an adult is a lot of doing jobs is drinking.
Ron: So it's been like seven days on the truck.
Ron: Yesterday, I accidentally ate three full English breakfast as well, so I've had to do a lot of digesting as well.
Laura: That doesn't sound like an accident.
Laura: That sounds amazing.
Ron: Well, we were in the hotel and I had a brilliant plan to get up in time for breakfast, eat a bunch and then go back to sleep, which was amazing.
Ron: Two plates of full English breakfast at this buffet.
Ron: And then we went to a cafe, and then Judith and our friend Ross put me on the spot ordering.
Ron: I panicked and ordered another thing called a mega breakfast about 3 hours later.
Ron: Yeah, that's what I'm going through.
Laura: It's one of the things I miss most now that I'm vegetarian, is full English breakfast.
Laura: Because if I'm going to eat meat, I like it to be really cruddy meat.
Laura: Like real cruddy.
Laura: I don't want a fine steak, I want a sausage that barely resembles but.
Ron: That'S more eco friendly.
Laura: You think?
Laura: Yeah, because it's waste products.
Laura: Practically dogfish.
Ron: It's all of the noses and buttholes and Grundles and stuff.
Ron: Like, it's not just the sort of the prime leg or the wing or whatever.
Laura: Yeah.
Laura: I still don't want to eat things at the moment.
Laura: We've got some thank yous to do, firstly, as always.
Laura: Thank you, podspike.
Laura: They're probably the reason you're listening to this, because they helped us choose a hosting site, which is where you put your podcast, and then it gets sucked into all the other places that a podcast can be.
Laura: That's right, isn't it?
Ron: Wrong.
Ron: Yeah.
Ron: And you might have seen, like, we were in the podcast of the week the other day.
Ron: No big deal.
Ron: But that's all.
Ron: Fod spike.
Laura: Yeah.
Laura: They wrote us press releases.
Laura: It's still us a little bit because we've made a nice podcast.
Laura: But also them.
Laura: It was them in a big way.
Laura: So thank you very much for podspike.
Laura: Also, we've got a massive thank you to Carol, who's made us a scrabble tableau.
Ron: Scrablo?
Laura: Yes, a scrablo.
Laura: So Carol has made us a framed art installation.
Laura: We'll put it on the Instagram.
Laura: But thank you so much, Carol.
Laura: It's our first fan art.
Laura: Ron, it is your first ever.
Ron: I've never had a thing made for me before and it's just dismissed.
Ron: It's my catchphrase.
Ron: It's basically all me.
Laura: Yeah.
Laura: Well, thank you so much, Carol.
Laura: We love it.
Laura: And we will pop it on the instagram this week.
Laura: Paisley Buddy has also on Twitter, has sent us a very cool interactive periodic table, which I'll put a link to it in the show description.
Laura: Thank you for showing us that, Paisley Buddy.
Ron: A big well done to Jenny, for being the person with the even less accessible definition of a metre.
Laura: Last week, I said a metre was about a wheelbarrow and Ron laughed a lot.
Laura: So we asked you on social media, how do you picture of roughly a metre?
Laura: And we got some interesting responses back.
Laura: Quite a lot of people just said what you said, Ron do.
Laura: They just picked it a metre ruler.
Ron: Yeah.
Ron: Including your husband paragon of sensibility.
Laura: No, he married me.
Laura: How can you possibly call him that?
Laura: Jenny offered us a buzzard's wing span.
Ron: Nonsense.
Ron: That doesn't help.
Laura: No.
Laura: You're going to choose that over a wheelbarrow?
Laura: You're full.
Ron: How many bars can you fit in a wheelbarrow?
Ron: Question.
Laura: Depends how argumentative they are about it.
Laura: A large step.
Laura: That's crazy, because one of Tom's large steps is way different to one of mine.
Ron: Yes, but I think that was Kevin, wasn't it?
Laura: I believe so.
Ron: If he's picturing one of Tom's largest steps instead of his own, then yes, he is mad.
Ron: But I presume he's imagining his own legs and body.
Laura: And also a guitar.
Laura: That was another option.
Laura: But I think a guitar is longer than a metre.
Ron: You think a guitar is bigger than a wheelbarrow?
Laura: Yeah.
Ron: That's the problem with this system.
Laura: Size is subjective.
Laura: So we've also had some brilliant puns.
Laura: Keep them coming.
Laura: We're enjoying those.
Ron: No, they need to stop.
Laura: What?
Laura: Why?
Ron: Can't be better at this than us.
Laura: Oh, they have to be.
Laura: Somebody has to be.
Laura: Ron, I'm going to delete your comment there in the show notes where you said, this needs to stop.
Laura: It's not keep them coming.
Laura: So let's jump into the episode now.
Laura: This is probably my favourite episode we've released yet.
Laura: I think this is the episode where the wheels really start to come off down in a big way.
Laura: We're going back to physics.
Laura: Yeah, maybe.
Laura: How many times you hear the word down in this episode?
Laura: And let's listen to Laura and Ron start to fall out.
Laura: Listen, Ron, how are you doing?
Laura: Because I'm tired and very grumpy and I'm just not in the mood for your s*** today.
Laura: I feel like this is just going to be a really angry episode.
Ron: This episode, I think, might really get you back up as well.
Laura: It's already up, though.
Laura: What was the last physics?
Laura: What was physics again?
Laura: Which one was that?
Laura: It's not atoms, is it?
Ron: No.
Ron: So that was my first question.
Laura: Stupid woman with the ball.
Ron: Yeah.
Ron: Can you remember what force is and what it's measured in?
Laura: Force is like it's force, isn't it?
Laura: You know what force is that?
Laura: I think it's measured in Newton's.
Ron: It is measured in Newton's.
Ron: Okay.
Ron: Why don't you try and not necessarily define forces in the vague concept of that, but what?
Laura: A force is like moving stuff or force?
Laura: I don't know another word for force.
Laura: This isn't thesaurus education.
Laura: I don't know, Ron.
Laura: I think it's just force.
Laura: It's just like what is doing a thing?
Laura: Oh, that is it.
Laura: It's for that?
Laura: Is that it?
Laura: I hate this.
Ron: All right, talk to me about a four day question.
Laura: Don't just rephrase the question in a different patronising way.
Laura: I just did that.
Laura: I just did talk to you about force.
Laura: I said it.
Ron: I'm asking a different question.
Ron: Imagine you are the woman throwing the ball.
Laura: I'm tired.
Laura: My arms tired.
Ron: What force could you apply to it?
Laura: What do you mean?
Laura: I could get, like, my arm.
Ron: The.
Laura: Ball, I'm throwing it with force.
Laura: I don't know what you're asking me for, Ron.
Laura: I don't know what the question is.
Laura: I'm going to throw the ball with my arm forcefully.
Laura: I throw it hard.
Laura: Is that it moved my arm fast.
Laura: Fast arm hysterical already.
Laura: I hate you.
Laura: And I don't know is this what we did last time?
Ron: So the first thing to know is what a resultant force is.
Laura: Moving?
Ron: No, I'm going to teach you this.
Ron: This isn't a guess thing.
Ron: Okay.
Ron: So basically, all of the forces that act upon an object can be distilled into one force, and that is the resultant force.
Ron: Okay.
Ron: So let's think about a Blue Planet plastic water bottle that says Spa Rain on it, sitting on a table.
Ron: What force on it?
Ron: Blue plastic bottle that says Spa Rain, I think.
Ron: No, that's just what I'm looking at.
Ron: Now, imagine that on a table.
Laura: Yeah.
Ron: What forces do you think are being applied to that bottle?
Laura: Like someone might want to drink from it.
Laura: What do you mean?
Laura: Gravity?
Ron: Yes.
Ron: So gravity is, in effect, pulling it down onto the table.
Laura: Yeah.
Ron: So what other force can you think because gravity is pulling it down, but the bottle is not moving?
Laura: No.
Laura: Because it's on the table.
Ron: Yeah.
Ron: So the table is effectively pushing up against gravity.
Laura: No, it isn't.
Laura: The table still.
Ron: But it's applying a force to the bottle.
Laura: No, I think it's just there.
Ron: But it is.
Laura: It's not, though, is it?
Laura: Because it's just a table.
Ron: Yeah, but it's applying a force to the bottle that counteracts the force of gravity.
Laura: No, it isn't.
Laura: It's just there in the way.
Ron: You're going to have to go with me on this.
Laura: No, I think science needs to go with me, that they are just f****** making things up to give themselves a job.
Ron: But then why wouldn't the bottle be moving if there was nothing?
Laura: The table is in the way.
Laura: I'm not saying the table is not stopping it.
Laura: It is, but it's not pushing up.
Laura: It's just there a static table.
Ron: But you agree that gravity is pulling down?
Laura: Yes.
Ron: So surely then you must agree that the table is counteracting that the table.
Laura: Is harder than the bottle.
Ron: Yes.
Ron: You must see that the table is equal and opposite to gravity because the bottle is not moving.
Ron: Yeah, and what's the opposite of pulling?
Laura: Stopping.
Ron: Don't be like that.
Laura: Why does it have to be the opposite?
Laura: It's not the opposite, it's just in the way.
Ron: Because gravity is pulling.
Laura: Yeah.
Ron: That needs to be counteracted.
Laura: No, it doesn't.
Laura: Not if you just stop it.
Ron: Yes.
Laura: I don't understand why it's got to be the opposite.
Ron: Because what do you think is stopping?
Laura: Crisps?
Laura: It doesn't mean I've stopped because I've started throwing up crisps.
Laura: It just means I'm not eating crisps anymore.
Laura: Why can't the table just be doing that?
Ron: Okay, imagine it's not a table, it's your hand.
Ron: You're holding the bottle.
Laura: Yeah.
Ron: Okay, and then what happens if someone, like, if you're holding something heavy and then someone takes that away from you and you don't really realise I said.
Laura: Thank you so much for taking no.
Ron: Your arms kind of, like, move upwards, don't they?
Laura: No, I'm not a cartoon character.
Ron: Yes, they f****** do.
Laura: But if my hand was lying on the floor and someone took something heavy off it, my hand wouldn't ping into the air.
Ron: No, because the floor is applying the force in that scenario.
Ron: But you see what I mean?
Ron: Like, if you were holding something I.
Laura: Don'T see what you mean in the slightest.
Laura: Otherwise, all the floor, like when I took things off the table, the table will be pinging up like a jelly table.
Ron: Why would it be?
Laura: Because you're saying it's pushing.
Laura: So then when it stopped pushing, it would be pinging up when you took the weight off it.
Laura: Mackie agrees with me.
Ron: But you see what I mean with the arm thing, right?
Laura: No, not in the slide, just.
Ron: Yeah, but you do because.
Laura: You can't just keep telling me I do understand.
Laura: I don't.
Laura: Ron, you're talking cobbledygook.
Laura: A table isn't pushing.
Ron: It is.
Ron: But why would it be different with your arm and a table?
Laura: You're the one that thinks my arm is made of jelly.
Ron: I never said a bean about jelly.
Ron: Right, but you understand that to hold something in the air, you're applying a force.
Ron: God, I honestly even on to the topic that was in the syllabus.
Ron: I'm trying to lay the f****** groundwork for that.
Laura: Right, okay.
Laura: My table, my desk is pushing my laptop up to the sky.
Laura: Fine, you win.
Ron: Not up to the sky, Laura.
Ron: It's just counteracting the force of gravity.
Ron: You know, that one of Newton's laws of thermodynamics for every reaction, there's an equal and opposite reaction.
Laura: So he thinks fine.
Ron: Okay, right.
Ron: Let me try to think of another.
Laura: Way to explain I don't care, Ron.
Laura: The table's pushing.
Laura: Fine.
Laura: If that's what you say, I believe you.
Ron: This is the whole thing.
Laura: Well, there we go.
Laura: I've learned it now what?
Laura: I mean.
Laura: Let's do another bit now.
Ron: We're moving on to resultant forces.
Ron: Resultant forces.
Ron: So basically what it is, is that all of the forces that act upon an object can be distilled into one force, like kind of averaged out.
Ron: But it's quite hard to explain that to you if you're going to deny a large proportion of the forces that are acting upon a thing.
Laura: No, not denying anything.
Laura: My table is pushing.
Ron: So I thought maybe it would be fun if you had a couple of situations and you told me what the resultant forces were in these situations.
Laura: I can't wait.
Laura: That does sound fun.
Laura: You're right.
Ron: Listen up, lord.
Ron: You need to stop being an art.
Laura: I said I do it.
Laura: I said it sounded fun.
Laura: Stop being rude.
Ron: Okay, could you try and tell me the resultant force when a ball rolls down a hill?
Laura: Down.
Laura: Moving downward motion.
Laura: What are you saying?
Ron: So let's think about all of the forces that are acting upon this ball, right.
Laura: Down.
Laura: Downness, yes.
Ron: So it's got gravity working against it.
Ron: What else?
Ron: Gravity is pulling it down.
Laura: Down, yeah.
Laura: The wind.
Ron: Yeah.
Ron: A bit of air resistance, friction.
Ron: That's kind of applying a force in the other direction, slowing it down.
Laura: I hit a pebble.
Ron: It's a smooth, flat.
Laura: Heat energy.
Laura: It's going down the hill.
Laura: Somebody through it.
Ron: Here's what we're going to do.
Laura: Kinetic energy.
Laura: Shut up.
Ron: Draw a diagonal line yes, sir.
Ron: Across on your page.
Ron: And then draw a ball on it.
Laura: Yes, I've done that.
Laura: Two points.
Ron: Okay, now we're going to draw arrows to represent the different forces that are being applied to this ball.
Ron: Okay?
Laura: Yeah.
Ron: So draw an arrow going from the ball pointing down, like down or down the slope.
Ron: Well, which way would gravity be pulling it?
Laura: To the core of the Earth.
Laura: No, not the Moon.
Laura: To the core of the Earth?
Ron: Yes.
Laura: What's the Moon doing?
Laura: Pulling us all to the sea?
Ron: In this world, there's no Moon.
Ron: We will cover the Moon in, like, eight years.
Laura: Okay, so down to the middle of the Earth.
Ron: Yes.
Ron: So on your diagram, what direction is that?
Laura: Down to the floor.
Laura: Down to the bottom of my page?
Ron: Yeah.
Ron: Just straight down?
Laura: Yeah.
Ron: So draw an arrow pointing straight down.
Ron: Maybe mark it with a G.
Ron: So we know that that's gravity.
Laura: That is gravity.
Ron: Then the next one you mentioned is wind.
Ron: Let's just roll that all into friction, because obviously the surface of the hill is going to be applying some friction as well.
Ron: Yeah.
Laura: Are you imagining the wind is blowing into the ball or from behind the ball?
Laura: Because I'm imagining the wind is blowing the ball down the hill.
Ron: There's no wind.
Ron: No, I said we're going to wrap that up into friction.
Ron: Okay, so there's no wind, there's just air resistance and friction.
Laura: Okay.
Ron: What would these things do to the ball?
Laura: Slow it down.
Ron: So they are applying a force going in which direction?
Laura: No, direction.
Laura: Stop.
Laura: Direction.
Laura: Direction.
Ron: No.
Laura: Stopping.
Laura: Stopped.
Laura: Slow down.
Laura: What are you wanting?
Laura: Stop.
Ron: Stop.
Ron: Not at direction.
Laura: I know, but it's not going the ground isn't saying, Go this way.
Laura: The ground is just saying, don't do it, please, isn't it?
Ron: Yes, but it is supplying a force in a direction that is up, kind of up.
Ron: The friction would be, I think, applying a force just going up the hill because it's slowing it down.
Ron: It's trying to stop it from rolling down the hill.
Laura: Friction.
Laura: Oops, I've written friction.
Ron: In your mind.
Ron: What?
Ron: Which direction on your hill would the ball be?
Laura: Moving down the hill.
Ron: Okay.
Ron: But the two force arrows that we've drawn on it so far, they wouldn't really make it move that way, right?
Ron: No, because they'd be making it move sort of down and a bit backwards.
Laura: Yeah.
Ron: So there must be some other forces being applied to the ball.
Ron: Could you hang on a guess at any of them?
Laura: I don't know all the fancy words for them, but it's down, isn't it?
Laura: It's going down the hill.
Laura: Did somebody throw the ball?
Ron: No.
Ron: We are just thinking about a theoretical ball that is Midwest.
Laura: Do you remember the advert where all the colourful bouncy balls go down the street in San Francisco?
Ron: Yeah.
Ron: With Josie Gonzalez.
Ron: Playing good, advert.
Ron: Stop thinking about that.
Ron: We're thinking about a theoretical for me.
Laura: To think of a hill, I think of San Francisco.
Ron: That's just lovely.
Laura: Do you know what for directed in San Francisco?
Laura: Princess Diaries.
Ron: Yes.
Ron: So we're thinking about a theoretical ball that is in the process of rolling down a hill.
Laura: Yes.
Ron: There is no story before or after that.
Laura: Okay.
Laura: So what do you want me to say?
Laura: Down.
Ron: I'm working upon this ball.
Laura: Well, down and the friction one.
Laura: Oh, I see what you mean.
Laura: Because the floor is being the table.
Ron: Yes.
Laura: Unless it was like a really heavy ball, it couldn't burrow through the floor.
Ron: Exactly.
Laura: So the floor is the table.
Laura: It's going up.
Ron: Well, which direction, do you think?
Ron: Straight up?
Laura: Yeah.
Laura: Well, no, probably at the same angle as the floor is.
Ron: Yes.
Ron: Perpendicular to the floor.
Ron: Very good.
Laura: What's that called?
Laura: Table?
Ron: Well, that's the force of the hill pushing upwards against the ball.
Ron: But I didn't really want to go down that nasty avenue again, pushing.
Laura: Okay.
Laura: I've drawn that arrow.
Ron: Okay.
Ron: So those are the three forces acting upon the ball.
Laura: So how are we going forwards?
Ron: Can you a picture of your diagram just so I could double cheque?
Laura: Just find out all the things I've done wrong in it.
Ron: Yes, but that's kind of the point.
Ron: If you could set that to me and then I can just double cheque that you got it right.
Ron: And then we can talk about the resultant force.
Ron: Okay, sure.
Ron: Yeah.
Ron: Okay.
Ron: Usually you do them with the arrows coming out of the ball, but all of the arrows are correct.
Ron: Cool.
Ron: So the resultant force is kind of the average of those three.
Ron: So you can imagine that the friction on the ball is quite low, right?
Laura: Yeah.
Laura: Because it's on the floor.
Ron: Yeah.
Ron: And it's rolling.
Ron: It's not skidding down the hill.
Ron: It's a ball.
Ron: It's rolling like it was a rubber trying to sled down a sandpaper hill.
Ron: Then the friction is going to be just enormous.
Ron: But it's not that.
Ron: That would be mad.
Ron: It's a ball.
Laura: That would be crazy.
Laura: Scientists would never do that.
Laura: Can you imagine the chaos?
Ron: Yeah, it might be easier for you to.
Ron: At least the way that my brain works.
Ron: Is it's easier to picture it if the arrows come out of the ball?
Laura: Why?
Ron: Oh, God, mackie just made a horrible noise.
Laura: Yeah, she's come over to Cheque I'm okay because I was shouting a lot.
Ron: I don't know.
Ron: Just give it a go with that and see if you can because I think it's easier to picture when the arrows are coming out, where the sort of the average of them all is.
Ron: Make gravity the biggest one, then the hill one a little bit smaller than the gravity one, and then make the friction one quite small.
Laura: Start in the ball, though.
Laura: Going up into the sky.
Ron: No, coming out of the ball and going down for gravity.
Ron: Coming out of the ball and going up for the hill one.
Laura: Yeah, well, that's not right though, because it's not the ball trying to fly up, is it?
Ron: We're just talking about things so stupid.
Ron: Okay.
Laura: I like my dog, Ron.
Laura: She's real.
Ron: So now it looks like a clock a bit.
Ron: So can you see now that you've got the hill force kind of pushing a bit to the left and then the gravity force coming down and then a little bit of friction?
Ron: What do you think the resultant force from that would be?
Laura: I'm scared to say it, Ron.
Ron: No, just give it a go.
Ron: I'm not going to be mean about it.
Ron: Down, straight down.
Laura: Down the hill.
Ron: Closer.
Ron: Yes.
Ron: Yeah, we'll go a bit down the hill, put it to the left.
Laura: Yeah, I know what a f****** ball does.
Laura: I just don't believe your claims that it's only happening because the hill is pushing it.
Ron: Why else would it be happening?
Laura: Then somebody threw it.
Laura: If a whole hill was pushing a tiny ball, it would know about it.
Ron: It does because it stays on the top of the hill.
Laura: Yeah, but that's just because the hill is made of tarmac.
Ron: It sounds like a horrible hill, but that hill is pushing.
Laura: I don't think it's pushing though, is it?
Laura: It's just there.
Laura: It's just not allowing it self to be pushed.
Laura: It's not pushing.
Laura: It's just not being pushed, you know?
Ron: No, I don't know.
Ron: It's not correct.
Ron: So the next one that we're talking about is Newton.
Laura: Is that who I've got to talk to?
Ron: I mean, the entire physics community, I think.
Laura: Okay.
Ron: Right.
Ron: Here's the next one.
Ron: A pendulum.
Ron: What forces do you think are acting upon the pendulum?
Laura: Gravity.
Ron: Yes.
Laura: Is there no wind again?
Ron: Yeah, no wind.
Laura: That's it then.
Laura: Just gravity.
Ron: So what's the pendulum doing?
Laura: Just hanging?
Ron: No, I said a pendulum swinging before, I think.
Laura: What swinging then?
Ron: Yeah, but the only force working on it is gravity.
Laura: Yeah.
Ron: What do you think it would be doing if actually, in reality, for a second, the only thing acting upon it would be gravity?
Laura: It would be falling to the centre of the Earth.
Ron: But it's not doing that because of the moon.
Ron: Bounce the moon out your life, mate.
Ron: It's not factoring in.
Ron: Okay, so the ball is not plummeting to the centre of the Earth?
Laura: Yes.
Laura: Because it's on a hill.
Ron: It's not from a hill.
Ron: It's a pendulum.
Laura: Well, why did you say the ball then?
Ron: It's a ball on a pendulum.
Ron: It's a pendulum.
Ron: Okay.
Ron: It's a clock pendulum.
Ron: The pendulum is not plummeting to the centre of the earth?
Laura: No.
Laura: Someone's holding it.
Ron: Let's say that.
Ron: Yeah.
Ron: Okay.
Ron: Someone's holding it.
Ron: Why would someone be holding a pendulum?
Ron: That doesn't make any sense.
Laura: They're hypnotising someone else.
Ron: So it's not on a clock.
Ron: Are you imagining, like, a pocket watch on a okay, I thought you meant like a pendulum inside a grandfather clock.
Laura: That's what I was picturing.
Laura: Someone's holding one of those hypnotising someone.
Ron: Someone's holding a pendulum from a few talking.
Laura: That's what jumped into my head when you said a pendulum.
Ron: Why?
Laura: I don't know.
Laura: I just thought, oh, swinging.
Laura: Wait a minute.
Laura: Newton's cradle.
Ron: Yeah.
Ron: Those are pendulums.
Laura: Yeah.
Laura: And Newton, he's the man we're talking about.
Ron: We're talking about a pendulum.
Laura: Yeah.
Laura: All right.
Laura: What do you want me to do?
Laura: Pin the pendulum to something.
Ron: Right.
Ron: Let's not have it be a weird person holding a part of a grandfather clock because that is honestly insane.
Ron: Let's think of it as just let's still have someone hypnotise someone.
Ron: Let's do it the normal way.
Ron: With a pocket watch on a string.
Ron: Okay?
Laura: Yeah.
Speaker UNK: Okay.
Ron: And now we're thinking about that when it is at the middle of its swing.
Ron: So it's right at the bottom.
Laura: Yeah.
Ron: Okay, so we've identified gravity is pulling on the pocket watch.
Laura: Yeah.
Ron: But the watch is not plummeting to the centre of the earth.
Laura: No.
Ron: So what other forces are working upon it?
Laura: Well, the magician's hand is pulling it.
Ron: Yes.
Ron: And that's attached by the chain.
Ron: Right.
Laura: You're thinking about it on a chain.
Ron: Yeah.
Ron: What would you think about it on?
Laura: Just a long metal stick.
Laura: Like a rod.
Ron: What fears?
Ron: I thought this was just something really pervasive in pop culture.
Laura: What are you typing about?
Laura: Who are you telling?
Ron: I'm not telling anyone.
Ron: I'm trying to find a picture of a magician hypnotising someone with a boggy watch to see if I'm losing my f****** mind.
Laura: Well, if it was a pocket watch.
Laura: I don't know, maybe a ribbon.
Ron: It's okay.
Ron: It seems like every image on Google backs me up.
Ron: That it would be on a chain.
Ron: That's fine.
Ron: We're talking about the pendulum when it's at the bottom of its swing.
Ron: Okay.
Laura: Yeah.
Ron: So gravity is pulling it down.
Ron: The tension in the chain is pulling it up.
Laura: Yeah.
Laura: Thing is, because of the way I've drawn my pendulum, it's hard for me to draw an arrow going up, coming off the pendulum.
Laura: It just looks like the whole pendulum is an arrow, but you could just.
Ron: Use the point on the arrow to kind of denote how far up that the force is, if you see why me?
Laura: Sure.
Ron: So when the pendulum is at the bottom of its swing, it is neither moving up nor down.
Ron: Yes.
Laura: Just like the grand or Duke of York.
Ron: Going to take that as a yes.
Ron: I didn't get the reference.
Laura: And when they were down, they were down, and when they were only halfway up, they were neither up nor down.
Laura: That song, you know that.
Ron: Okay, sure.
Laura: Oh, the grand old Duke of York, he had him there.
Laura: No.
Laura: What's the tune?
Laura: At the beginning of it, he marched them up to the top of the hill and he watched them down again.
Laura: That's not quite right, though, is it?
Ron: I'm going to send you down.
Ron: We are six lines into my research.
Laura: Yeah.
Laura: We've only got ten more minutes.
Ron: Yeah.
Ron: We're just going to get through these results and force bits, and then we're going to have because after this, I was about to introduce a new concept to you called work.
Ron: I haven't got enough grey hairs already.
Laura: I'm working really hard.
Ron: So do you agree that at the bottom of it swing, the pendulum is not moving up nor down?
Laura: Yes, I said that.
Ron: You just started talking about Prince Andrew or something.
Laura: No.
Laura: Yeah.
Laura: He was Duke of York, actually, wasn't he open?
Ron: Yeah, he was.
Ron: It was a good joke.
Laura: Yeah, I said that.
Laura: Yeah.
Ron: So the tension in the chain and the gravitational force put it down equal.
Ron: Okay.
Laura: At that point, yes.
Ron: At that point, yes.
Ron: When it keeps on swinging, they then wouldn't be equal.
Ron: No, of course not.
Ron: Because then it would start moving up or down.
Laura: And then it would be up or.
Ron: Down at the bottom of its swing.
Laura: Yes.
Ron: Is the pendulum moving?
Laura: No.
Ron: Yes, it is.
Ron: Yes, it is moving.
Ron: What force do you think is making it move at that point?
Laura: Is it just a choice of these two forces?
Ron: No.
Laura: Momentum, force.
Ron: Yes.
Laura: Pulled that out of my b*******.
Ron: Well done.
Ron: Yes.
Ron: The momentum is moving it.
Ron: So what do you think the resultant force, when you take into account those three things, what does that look like.
Laura: Swinging.
Ron: In terms of an arrow?
Laura: Like a big smiley face, curly side, left and right, diagonal.
Ron: Please don't just say things.
Laura: I don't like silence, though.
Laura: I like to fill it up, just.
Ron: Have a bit of a think about it.
Laura: What do you mean?
Laura: I've drawn an arrow.
Laura: It's got a bend in it halfway along.
Ron: Forces have to act in a direction.
Ron: They can't have bends in them.
Ron: The tension from the chain and the gravity.
Ron: One's pulling up, one's pulling down.
Ron: And then you've got the momentum, let's say going to the left.
Laura: Yeah.
Ron: Okay.
Ron: What do you think the average of those three forces is?
Ron: That leads leaves us with the resultant force?
Laura: A bit of left, a bit up, a bit down.
Laura: It's all of them, isn't it, on a pendulum?
Laura: I don't understand.
Laura: Some of each, they just take it in turns.
Laura: On a pendulum, they all have a go.
Ron: But we agreed just now we agreed.
Ron: You agreed with me.
Laura: I'm not trying to argue with you, but a pendulum just swings all around.
Laura: So I can't do one arrow to represent everything a pendulum is getting up to?
Ron: Yes, you can.
Laura: Not a straight one.
Ron: Yes, because we're talking about the pendulum at this specific point.
Laura: It's going stop, isn't it?
Ron: No.
Ron: Who.
Ron: It hasn't.
Ron: Right, so we agreed that stop saying we agree.
Ron: But we did f****** agree, so don't backpedal now.
Ron: Don't want to be known as a deal world trip.
Ron: I'm not at the bottom of its swing.
Ron: The ball is not moving up nor down.
Ron: Correct.
Ron: It's just moving sideways.
Laura: I found some wires sticking out of my wall.
Laura: What did you say?
Laura: Sorry?
Laura: The pendulum was what at the bottom?
Laura: It's down at the bottom of the hill?
Ron: Yes, it's at the bottom of its swing.
Ron: So at this point, it's not moving up or down because the tension in the chain and the gravity pulling it down at that moment are equal and opposite.
Ron: Right.
Ron: So when we're talking about resultant forces, what are they going to do?
Ron: Okay, think about it this way.
Ron: What if one of them was so maybe if we put it into numbers, it would make more sense.
Ron: Right.
Ron: So let's say that the gravitational force pulling it down is ten newtons pulling directly down.
Ron: The tension in the chain is pulling up ten newtons as well.
Laura: Yeah, it stopped.
Laura: I've already said that.
Ron: So they cancel each other out, right?
Laura: Yeah.
Ron: So if those two cancel each other out, what is the result?
Laura: In force stopping.
Ron: But it's not f****** stopped, has it?
Ron: Because it's still moving.
Laura: Well, then, why?
Laura: Because of the momentum.
Ron: The other one.
Ron: That's all I wanted you to say.
Laura: You can tell me to think about that one.
Ron: I told you to think about all of them.
Laura: Is this going to go left, then?
Laura: Really, isn't it?
Ron: Yeah.
Laura: Why can't you just tell me that to begin with?
Ron: Because f****** 14 year olds.
Laura: They'Re not doing anything else, are they?
Laura: 14 year olds aren't trying to pay the mortgage and drive places and find out what Ad blue means and where.
Laura: To put it in their car.
Laura: If anybody knows, can you please let me know?
Laura: Because it's been flashing for ages and I don't know what to do.
Laura: So of course they've got time to learn this s***, whereas I'm busy.
Ron: So we're going to do one more at the end.
Laura: No, I'm finished now.
Laura: I'm bored and it's stupid and I hate it.
Ron: Christ.
Laura: That was dog s***.
Laura: Physics is the worst one.
Laura: Sorry, Ron.
Ron: Sorry.
Laura: It's not right.
Laura: So it's really hard to learn because the hill isn't pushing and the pendulum isn't going left, it's going up and left and back down.
Laura: Okay, we'll see in a bit for the quiz.
Ron: Yeah.
Ron: So there's only two points on offer.
Laura: Okay.
Ron: Because to be honest, I couldn't face and there was so little content in the last episode that there was nothing else for me to make questions out of.
Laura: I bought myself three weeks, though, to get on board with this idea that a hill is cuddling a ball.
Ron: For one person?
Laura: No, the opposite.
Laura: Pushing a ball away.
Ron: Yes.
Ron: Laura, what is a resultant force?
Laura: The stuff that ends up happening.
Laura: The thing that happens.
Ron: Give me more like.
Laura: A ball is on a hill and gravity is pulling the hill into the floor and the hill is pushing the ball into the sky and friction is there and the ball rolls down the hill.
Ron: But what is the resultant force?
Ron: A couple of two things about the ball.
Ron: What is the resultant force?
Laura: I know that you keep repeating that question and looking at me, like, really intently.
Ron: What is a resultant force?
Ron: You can work it out from the name of it.
Laura: That's why I said It's the thing that's happening, the result.
Ron: That's not what you said.
Laura: I did.
Laura: I said, the thing that happens.
Ron: I don't think I can give this to you.
Laura: Why not?
Laura: You know that I know what I am.
Laura: I said, It's the thing that ends up happening.
Ron: Look, Laura, I'd love to give you the point.
Laura: No, you wouldn't.
Laura: Look at your stupid face smirking away.
Laura: This isn't how you give me the point, then.
Ron: It's not how school works.
Laura: We're not in school.
Ron: You don't get points for knowing stuff.
Ron: You get points for parroting back the thing that they want you to say.
Laura: And I did.
Laura: I said, It's the thing that ends up happening.
Laura: Yeah, but that's further away.
Laura: How is that further away?
Laura: It's a result.
Ron: All of the forces that act upon an object can be displayed as one resultant force.
Ron: It's when you match them all together, you average them all out.
Ron: What force is left at the end?
Laura: Yeah.
Ron: That is not the same as the thing that ends up happening.
Ron: Because in the example that you gave a ball rolling down a hill, the thing that ends up happening is the ball rolling down the hill.
Ron: The resultant force is like a diagonal line pointing downwards.
Laura: Yeah, that's because there's more down than there is hill push?
Laura: Yeah, there's a little bit of hill push.
Ron: I'll give you half a mark.
Laura: Give me the whole down mark.
Ron: Absolutely not.
Ron: Half a mark.
Ron: Are you ready for question number two?
Laura: Who can ever tell?
Ron: A small porcelain dog is sat on a large oak table.
Ron: What is the resultant force acting upon the dog?
Laura: The oak table is pushing the dog up and gravity is pulling it down.
Laura: The resultant force is that the dog is not floating in the air.
Ron: Close.
Ron: Try again.
Laura: The resultant force is that the dog is on the log.
Laura: Was it a log?
Ron: What?
Ron: Was it a large oak table.
Laura: A large oak table.
Laura: The dog is just on the large oak table.
Laura: It's just on it?
Ron: Yes.
Ron: So what's the resultant force?
Laura: Down.
Laura: Stop.
Laura: Stoppage?
Laura: Yeah.
Ron: There isn't one.
Laura: Stillness.
Ron: There isn't one.
Laura: I hate you when you do these trickos.
Laura: It's not fair, do you know that?
Laura: It confuses me as much as it is without doing trick questions.
Ron: I just thought, because we literally talked about this last week, you might have.
Laura: Got it, you know that I hang out my headphones during this and I walk away so angrily that I then sort of, like, obtusely forget everything we've done, but cancels it.
Ron: Cancels out.
Ron: The force of gravity is the force of the table.
Ron: They just cancel each other out.
Ron: Nothing happens to the top.
Laura: Yeah.
Ron: Which I'll give you another half a month for.
Ron: Stop.
Laura: I didn't say stop.
Laura: I said it doesn't stop it.
Ron: First you said down, so I think I'm being a bit lenient, to be honest.
Laura: Are you done?
Ron: Yeah.
Ron: That's the quiz.
Laura: That's it.
Laura: It's got physics garbage and I hate it.
Ron: Tell us at home how you did.
Ron: Did you get the full two points?
Laura: Did you say exactly the words that Mutant Ron needed you to say?
Ron: Did you answer the question?
Laura: I answered the question.
Ron: You make impassioned noises to kind of indicate you know what I'm talking about.
Laura: My science is bullshit because I know that a dog sat on a table doesn't, like, fall through the table and stuff, and I know how a ball goes down a hill, but if I don't say exactly the right type of down, I don't get the point for it, and that is stupid.
Ron: So are you asking for these lessons to be just like, what happens if you put a ball on a hill and then A, for me to clap when you say it rolls down, and B, for anyone to listen to them?
Laura: No.
Laura: We could have a chat about we could make it more like my degree was and then we have a chat about how the ball might be feeling as it goes down the hill.
Ron: Yeah.
Ron: How it was feeling in the context of the time that it rolled down.
Laura: How the witnesses looking at the ball rolling down might perceive the balls rolling in a different way.
Ron: Sure.
Ron: How it might be different if the Basalo man pushed it down a hill in gangland Chicago.
Ron: Something like that.
Laura: Yeah.
Laura: You know, useful stuff.
Laura: So that was a slog.
Ron: Yes.
Ron: Listening back.
Ron: More of a slog than I remember.
Laura: Yes, more of a slog for me, too.
Laura: And what's really sad is I've now recorded that with you.
Laura: I've edited it once, I've edited it twice for the second draught and I've listened back to it there and I still don't believe.
Ron: And now, on top of all of this, we're putting it out into the general public.
Laura: Do you know what, though?
Laura: I just have in the back of my head, though, when I was explaining this to dad and he went, well, it's not pushing.
Laura: And I was like, yes, dad agrees with me.
Laura: So we would normally ask you, how did you get on?
Laura: In the quiz, there were only two questions.
Laura: So I got 50% of the marks available, which is higher than a lot of my scores, so I'm fine with that.
Laura: Although getting half of each two points is a hard way to get 50%.
Laura: So there we go.
Laura: Let us know what you think.
Laura: What feedback do you have from us?
Laura: You can contact us on Lex education on all platforms TikTok, Instagram, Facebook and Twitter.
Laura: We're also on YouTube and the transcripts are available on our blog spot.
Laura: If you want to read along, you can email us, lexeducation@gmail.com, if you've got something to say that you don't want to be in the general public.
Laura: But bear in mind, we'll probably read it out here, so it will come around.
Laura: Our big question of the week is going to have to be if someone asks you to picture a pendulum, what do you picture?
Ron: Absolute batch it.
Ron: You are picturing a Rod mad.
Ron: Everyone please get in touch and let me know how right I am.
Laura: So there we go.
Laura: We'll be back to biology next week.
Laura: Thank goodness biology is fast becoming like a floating piece of driftwood in a sea of anarchy.
Laura: But we hope you've enjoyed physics too, and we will see you next week.
Ron: Class dismissed.
Laura: You got to say it in your voice.
Ron: Class dismissed.
Laura: Oh, my door slam.
Laura: Just as you said it.
Laura: It was so authoritative.
Laura: Do one more.
Ron: Class dismissed.
Laura: You sound like a ghost.
Ron: First.
