Show that the work done by a force is given by theproduct of the force and the component of thedisplacement along the force.

Answer»

Suppose a forceFacting on a body causes a displacements. The angle between force and displacement isθ.Then,work done by the force is given byW=F.s=Fs cosθor W=F (s cosθ)Where scosθ is the magnitude of projection of displacement s along the forceF.
