Question

Underline the correct alternative:
When a conservative force does positive work on a body, the potential energy of the body increases/decreases/remains unaltered.

Answer 1

Decreases

A conservative force does a positive work on a body when it displaces the body in the direction of force. As a result, the body advances toward the centre of force. It decreases the separation between the two, thereby decreasing the potential energy of the body.
