Question

$kg{ms}^{-1}$ is the SI unit of

• A. Impulse
• B. Force
• C. Angular velocity
• D. None of these

Answer 1

The correct option is A Impulse

Impulse $\left(I\right)$ imparted to the body is equal to the change in linear momentum $\left(\Delta p\right)$ of the body.

Impulse, $I=\Delta p$

Thus momentum has the same units as that of impulse. Since momentum has S.I. unit as $kgm{s}^{-1}$, impulse also has S.I. unit as $kgm{s}^{-1}$.
