When the force retards the motion of body, the work done is : |
Zero Negative Positive Depends upon the displacement |
Negative |
Work done is given by : \(W = \vec{F}.\vec{S} = FS \cos {\theta}\). For retarding force, F = negative. Thus, when the force retards the motion of a body, the work done is negative. |
