Text z Príbehu
- Šmykľavka: 1
- Well, I have a pen and paper here in my bag we can go get the pencil and paper in 2 minutes
- I left my pencil in the room . I wonder how far the distance if from the shop
- Šmykľavka: 2
- Yeah! You my friendhave fast reflexes
- Wow that dropped so quickly!The ball fell in 5 seconds that means the cliff is high
- Šmykľavka: 3
- That ball had some serious velocity. Is there any way we can find out just how fast?
- Well I am no Einstein but I have a timer or a clock in my class so we can check
- Šmykľavka: 4
- How do you know all these things?
- Well I payed attention in school. But really it's just the laws of physics. Gravity is constant so with a little digging we can find our answers to a lot of our questions
- Šmykľavka: 5
- Well yes of course but not in the way you think. Mass doesn't affect how fast gravity pulls it down, but rather how much air resistance affects it
- But, what about weight? Doesn't that play a role?
- Šmykľavka: 6
- That's basic s of air resistance ! air resistance is force that acts opposite to an object moving through air
- Oh so weight doesn't afffect gravity but air resistance does? So we weren't accounting for air resistance then?
