A force of 7 N acts on an object. The displacement is, say 8 m, 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?

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
