Question
A freely falling object eventually stops on reaching the ground. What happenes to its kinetic energy?
✓
Answer
As the object hits the hard ground, its kinetic energy gets converted into:
- Heat energy (the object and the ground become slightly warm).
- Sound energy (sound is heard when the object hits the ground).
- Potential energy of configuration of the body and the ground (the object and the ground get deformed a little bit at the point of collision).
