Work:- Work done W is defined as the dot product of force F and displacement s.
W = Fs
= Fs cos θ
Work done by the force is positive if the angle between force and displacement is acute (0°<θ<90°) as cos θ is positive. This signifies, when the force and displacement are in same direction, work done is positive. This work is said to be done upon the body.
