Question Question 1
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?
Given,
Force (f) = 7 N
Displacement (S) = 8 m
As,
Work done = Force × Displacement
Substituting we get,
W = 7 × 8 = 56 Nm or 56 J
Hence, work done = 56 J
