Question

When a force retards the motion of a body, what is the nature of work done by the force? State reason. List two examples of such a situation

Answer 1

The work done by the force is negative because this force acts opposite to the direction of movement of the body, thereby hindering the motion. 

Example: 

1. Work done by the force of friction acting opposite to the direction of football. 

2. Work done in Tug of war by losing team.
