Did you find that a single ball never bounced back to the height at which you released it, regardless of the ball you used? During a collision, some of the ball's energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height.

This bounce is caused by air that's pumped into the ball. As the air pushes against the inside of the ball it creates pressure.

What is the tennis balls equation?
