Question:

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

Answer:

When an object falls freely towards the ground, its potential energy decreases and kinetic energy increases. When a free falling object hits the ground, its kinetic energy becomes zero and its potential energy becomes maximum. The kinetic energy changes into heat and sound energy while the object comes to rest.
