Why does a ball bounce?

A ball, falling through space, loses potential energy and gains kinetic energy. This is a way to say (in Physics equations) that it goes faster the longer it falls. When the ball strikes a hard surface, the ball is deformed and changes all the kinetic energy to elastic energy. This energy then changes back to kinetic energy as the ball recovers its shape. This is an example of an elastic collision.

There is some loss due to air resistance and thermal loss in the conversion from kinetic to elastic and back again, but the ball acts as a good demonstration that energy is conserved in physical processes.
