When we say work is done by a force, it means that the force has provided energy to move an object in the direction of the force. The work done by a force is calculated as the force multiplied by the distance moved in the direction of the force. If the force is in the same direction as the displacement, positive work is done. If the force is in the opposite direction, negative work is done. If there is no movement (no displacement), no work is done.
