A force of 5 N is acting on an object. The object is displaced through 2 m in the direction of the force (Fig. 11.2). If the force acts on the object all through the displacement, then work done is 5 N × 2 m =10 N m or 10 J.

Answer:
10 J
Explanation:
W=F✖s
=5N✖2m
=10J
In the SI system, the unit of force is (N) and the unit of displacement is metre. Thus, the unit of force is Newton-metre. This is called Joule

Answer:
F = 7 Newtons
Displacement s = 8 m
As the force and displacement are in the same direction, the work done is the product of magnitudes of force and the displacement.
work done = 7 N * 8 m = 56 Newtons
