Question

Which one of the following physical quantities is represented by the shaded area in the given graph?

• A. Torque
• B. Impulse
• C. Power
• D. Work done

Answer 1

The correct option is D Work done

Work done by a force is given as

$\int \overrightarrow{F}.\overrightarrow{s}$

Thus the integral is the area under a curve with $F$ and $s$ as the coordinates.

Hence area under the given curve gives the work done.
