Question

Area under velocity-time graph depicts a physical quantity that has the unit _____.

• A. $m$
• B. $m{s}^{-1}$
• C. $m{s}^{-2}$
• D. $s$

Answer 1

The correct option is A $m$

We know, $velocity=\frac{displacementofthebody}{timetaken}$

i.e, $v=\frac{d}{t}$, where $v$ is the velocity in $m{s}^{-1}$ and $t$ is the time taken in $s$.

$⟹d=v\times t$

Hence, the area under a velocity-time graph gives the displacement of the body. The S.I. unit of displacement is $m$.
