Work Formula

Work is said to be done when a body undergoes displacement. It is denoted by W.

Work Formula is given by
F = force applied and
d = displacement.
Work formula is used to calculate work done, force or displacement in any problems. It is given in Nm.

Work Problems

Below are problems on work which helps ou to understand the concept better.

Solved Examples

Question 1: Calculate the work done if 10 N of force acts on the body showing the displacement of 2m?
Given: Force F = 10 N,
          Displacement d = 2m,
Work done W = F $\times$ d
                     = 10 N $\times$ 2m
                     = 20 Nm.

Question 2: Calculate work done for 2 newton force and 3 metre displacement and angle between force and displacement is 45 degree?
Given: Force F = 2N,
          Displacement d = 3m,
          $\theta$ = 45o
Work done W = Fd cos $\theta$
= 2N $\times$ 3m cos 45o
= 3.51 Nm.
