What is Work

Work the work done by a force acting on a body is the product of the force and the distance moved by its point of application in the direction of the force. If a force f acts in such a way that the displacement s is in a direction that makes an angle 6 with the direction of the force, the work done is given by: w = f • scos9. Work is the scalar product of the force and displacement vectors. It is measured in joules.
