Hey Friend,

Work is said to be done only, when a force or its component causes a displacement in its own direction. 

Factors determining work done by a body -

1. There must be a force acting on the body.

2. The force acting on the body must cause some displacement.

3. The displacement must be in the direction of resolved component of force.

If any of the above conditions are not satisfied, no work is done.

Hope it helps!
