Work is one of the ways of transmitting energy between bodies.
To carry out work it is necessary to exert a force on a body and that the body moves.

The work
, W, of a force on a body is equal to the product of the component of the force in the direction of the movement, Fx, times the displacement, s, of the body

W=Fx.

Work, W, is measured in joules (J). Force is measured in newtons (N) and displacement in metres (m).
