Question

from where does the ping pong ball get the kinetic energy for motion after striking the floor?

Answer 1

Answer:

The answer lies in how far the ball has dented inward due to its collision with the floor. As it falls, the ballconvert the energy stored in the force of gravity-- gravitational potential energy -- into the energy of motion--kinetic energy. By the time it reches floor, ball is traveling quickly and it hits the floor hard

Hope it helps you

Answer 2

Answer:

Explanation:

If you're dropping a projectile into sand, the potential energy that you began with ends up being converted into kinetic energy (from the sand thrown out from the collision), sound energy, and thermal energy. Ultimately, the thermal energy is the only surviving energy after any appreciable time though
