Question:- A force of 7 N acts on an object. The displacement is say 8m, in the direction of the force. Let us take it that the force acts on the object through the displacement. What is the work done in this case?

Answer:-

When a force F acts on an object to displace it through a distance S in its direction, then the work done W on the body by the force is given by:

Work done = Force — Displacement W = F — S Where, F = 7 N S = 8 m.

Therefore, work done, W = 7 — 8 = 56 Nm = 56 J

Hope this helps you ☺️
