Question.
A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force (see fig.). Let us take it that the force acts on the object through the displacement. What is the work done in this case ?
A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force (see fig.). Let us take it that the force acts on the object through the displacement. What is the work done in this case ?
Solution:
Given, force = 7 N ; displacement = 8 m
Work done = Force × Displacement
$=7 \times 8=56 \mathbf{J}$
Given, force = 7 N ; displacement = 8 m
Work done = Force × Displacement
$=7 \times 8=56 \mathbf{J}$
