Answer:
The tennis ball stops bouncing due to energy dissipation in the compression and decompression process.
Explanation:
When the tennis ball collides with the ground, some of its energy is dissipated in the compression and decompression process. This process keeps on repeating and then a time comes when all of the elastic energy in the ball is exhausted and the ball stops bouncing. At this point, the elastic energy stored in the ball is so small that it cannot overcome its own weight therefore, it stops bouncing.
