In physics, the measure of energy transfer that occurs when an object is moved over a distance by an external force, some component of which is applied in the direction of displacement.
For a constant force, work W is equal to the magnitude of the force F times the displacement d of the object, or W = Fd. Work is also done by compressing a gas, by rotating a shaft, and by causing invisible motions of particles within a body by an external magnetic force. No work is accomplished by simply holding a heavy stationary object, because there is no transfer of energy and no displacement. Work done on a body is equal to the increase in energy of the body. Work is expressed in units called joules (J). One joule is equivalent to the energy transferred when a force of one newton is applied over a distance of one meter.
