100 POINTS!! ANSWER ALL PLEASE, AND EXPLAIN YOUR RESPONSE! Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.

The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.

They do the following experiment:

**Written Response** What can they conclude from this experiment? Why?

I think the height of the ramp affects the distance that the ball can go, but the size doesn't affect it

and as you decrease th height of the ramp it will look like straight thing, when it look like that the ball might need a little force in order to get speed also to go far

but in this condition the size can affect the ball distance it also depends on how much you give to it

Thank you !
