Question

When an object falls freely towards earth, then its total energy remains constant.

• A. True
• B. False

Answer 1

The correct option is A True

1. Consider a ball is in free fall, gravity is the main force acting on it.
2. As a result, we may apply the concept of mechanical energy conservation.
3. The ball has potential energy but no kinetic energy initially.
4. As it falls down potential energy gets converted into kinetic energy.
5. But the total energy (the sum of the KE and the PE) of the falling object remains constant and equal to the initial PE.

Hence, the given statement is True.
