A force of acts on an object. The displacement is, say , in the direction of the force (Fig. 11.3). Let us take it that the force acts on the object through the displacement. What is the work done in this case? Let us take it that the force acts on the object through the displacement. What is the work done in this case?
The work done is given by :
or
Thus the work done by the force is 56 J.
