Hello friend!!
Rajdeep here....
When you apply force to an object and the displacement of the object occurs (takes place) in another direction, the work done is negative.
Work done in that case = F S cos A
where A = 180 degrees
So, work done = F S cos 180
= F S (-1) [Since, cos 180 = -1]
So W = -(FS) is the expression.
Thanks!
