When force is applied on an object, then the object responds to the applied force in one of the two ways: it can either remain in its original state/position or if the force is sufficient enough then it can move.
If the applied force moves the object then work is done on the object. It can be expressed as:
Work done = Force * Distance
Thus, When one applies a force over a distance causing the object to move in response to the force they have shown work
