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 SI unit as $kgm/s$, thus impulse also has SI unit as $kgm/s$.
