If force acting on a body is plotted along y s and displacement covered as result is plotted along as, then work done is given by
Correct answer: C. Area under the curve
- A. Each point on the curve
- B. Slope of the curve
- C. Area under the curve
- D. None is true
Explanation
This is the correct option. The work done is equal to the area under the curve on a force-displacement graph. This is because work done is the integral of the force with respect to displacement.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
