Question

When an object is dropped from a height, its potential energy ______ and its kinetic energy ______ till it reaches the ground.

• A. decreases
• B. increases

Answer 1

1. When an object is dropped, its height from the ground decreases, hence its potential energy also decreases.
2. As the velocity increases while going downward, its kinetic energy increases.

Hence, When an object is dropped from a height, its potential energy decreases and its kinetic energy increases till it reaches the ground.
