A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force (Figure). 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
