Bouncing Balls

Some balls bounce better than others.

A particular ball can be characterized by its

The ratio of its rebound speed Vf to its collision speed Vi

Scientists have found that, for most balls, this speed ratio

The amount of kinetic energy transformed at impact is called

This java applet shows you the effects due to

1. You can enter different value of coefficient of restitution as(Vo/Vi).

2. You can change the initial velocity Vx of the ball.

3. Press Start button to start/restart animation.

4. Press Reset button to reset parameters to its default value.

5. Press the mouse button to pause the animation

6. The mouse coordinate (X,Y) will be shown when its inside the window.

You should be able to get some graph like this (click me).

Your suggestions are highly appreciated!
