Question

A force of 7N 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 throughout the displacement. What is the work done in this case ?

Answer 1

Here, force acting on the object, F = 7N displacement in the direction of the direction of the force, s =8m Since F acts on the object throughout the displacement, it is constant. Work done by the force, i.e.,
`W = F xx = 7N xx 8m =56 J`
