W = F. S
Work is zero either if F is zero or S is zero.
W = F. S cos theta
Work is zero if theta = 90°.

If angle between force and displacement is 90 degree then the work will be zero
example -If porter carrying some load on his head and moves horizantally or straight then the work will be positive.
