(Physics) A manifestation of energy; the transfer of energy from one physical system to another expressed as the product of a force and the distance through which it moves a body in the direction of that force.
The amount of energy transferred to or from a body or system as a result of forces acting upon the body, causing displacement of the body or parts of it. More specifically the work done by a particular force is the product of the displacement of the body and the component of the force in the direction of the displacement. A force acting perpendicular to the bodys displacement does no work on the body. A force acting upon a body which undergoes no displacement does no work on that body.
A measure of the result of transferring energy from one system to another to cause an object to move. Work should not be confused with energy (the capacity to do work, which is also measured in joules) or with power (the rate of doing work, measured in joules per second).
Work is equal to the product of the force used and the distance moved by the object in the direction of that force. If the force is F newtons and the distance moved is d meters, then the work W is given by:
W=Fd For example, the work done when a force of 10 newtons moves an object 5 meters against some sort of resistance is 50 joules (50 newton-meters).
