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

Yeah! You my friendhave fast reflexes
Wow that dropped so quickly!The ball fell in 5 seconds that means the cliff is high

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

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

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?

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?
