A freely falling object eventually stops on reaching the ground. What happens to its kinetic energy?

Text Solution

Verified by Experts

When the object is falling freely, its potential energy changes into kinetic energy. When the object falls on the ground, the kinetic energy becomes zero. It changes into heat energy and sound energy.
