## icetea 2 years ago HEIGHT: PLEASE HELP How does the size of the ball affect the height the ball bounces? What affect, if any, does the size of the ball have on the common ratio?

1. timo86m

do you have any formulas for us?

2. icetea

I had to drop three different balls from a height

3. timo86m

and what is the common ratio?

4. icetea

and record the heights, I'm just not sure how to answer that question

5. icetea

they are vary but ball one is .033, ball 2 is .44, and ball 3 is .722

6. timo86m

and how far did each ball bounce?

7. icetea

8. timo86m

maybe by common ration they mean height/size of ball or reciprocal of it.

9. timo86m

so the 1 2 3 for 1 it is always 18 since that is where you dropped it from? 2 is the bounce and 3 is the second bounce?

10. icetea

yes @timo86m

11. icetea

would the size affect the height of the bounces??

size indeed affects the bounce of the ball, there are lot of factors besides that, if you talk about bouncing at a place where there is gravity then following factors will affect bounces: -- weight of the ball --size of the ball, as the smaller size of the ball will have less air drag so it will bounce more because of less drag force --material of the ball, if its density is less it will bounce for a longer time --shape of the ball, if its smooth it will bonce less compare to the ball with some kinda different design on it -- think your gona get more ;) babe
