What is the condition for a force to do work on a body?
First condition is that there must be some displacement in the body. If you apply force and body does not move, the work done will be zero.
Second condition is that direction of force should not be perpendicular to the direction of motion. You will learn more about this condition in higher grades.
In the above mentioned conditions, work done will be zero.
