Answer:
Mechanical work is the amount of energy transferred by the force. In physics, we define it as scalar product of force and displacement.
If force is applied but the object doesnt move, no work is done ; if a force is applied and the object moves; then work is applied.
Work: Pushing a car horizontally from rest; shooting a bullet (the powder does the work)
