When you hold a ball up in the air, it develops potential energy because gravity wants to pull it down. As the ball is dropping, that potential energy became kinetic energy, but loses some energy because of friction with the air. At impact more energy is lost to the ground via thermodynamics (heat loss) and deflection (strain energy transfer). The ball bounces back up with the remaining energy. Something like that, better to ask a physics professor in high school or college :)

Tennis balls are made of rubber and contain compressed air.
Both the rubber and compressed air cause the ball to bounce when dropped.

A tennis ball is a spherical spring that can't bounce down unless you play tennis on the ceiling.
