Gravity!

Playing around with gravity and speed in these simple ball interactions.

Click the balls to stop and start them bouncing. Gravity and speed varies according to how long you leave them to bounce and how they bounce in accordance to each other. If you leave them they will eventually cease to bounce.

And the first one I did was a simple click and the ball starts, click again and it stops type thing.
