Let us consider body moves a distance S due to the force F.
Hence the work by the body W = FS
If the force is not along the direction of displacement,then the work by a body for travelling a distance S will be -
where is the component of the force along the direction of displacement.
As per the question the power P is given as -
Hence alternative definition of power P = F.V
