When the energy is transferred to or from an object by the application of force due to displacement is called work displacement. The product of the magnitude of the force acting on the body and the displacement in the direction of the force is called the work done of the object. Work done is zero if force acting on any object but no displacement takes place. So take this quiz and know more about work and energy.
