Question

in reality, the tennis ball will never bounce back to exactly the same height, but less. why? there is friction with the air as the ball falls (air resistance). all of the above are true. the ball compresses when it hits the floor, and that produces a little bit of heat. some of the balls potential energy has been changed to other forms like heat and sound. rewatch submit

Explanation:

Air resistance converts kinetic energy to heat during fall, compression on impact generates heat, and overall energy is lost to non-mechanical forms (heat, sound). All options describe valid energy loss mechanisms, so "all of the above" is correct.

Answer:

all of the above are true.
