What is linear momentum ? Write its $SI$ unit.

Option A

Option B

Option C

Option D

Solution

Product of mass and velocity of body is called its linear momentum.

$\therefore$ Linear momentum (P),

$\mathrm{P}=\text { mass } \times \text { relocity }$

$p=m v$

Momentum is vector quantity and its direction is in direction of velocity. $SI$ unit of momentum $\mathrm{kg} \mathrm{ms}^{-1}$ or $Ns$ $CGS$ unit of momentum is $\mathrm{g}\; \mathrm{cms}^{-1}$ Dimension of momentum is $\left[\mathrm{M}^{1} \mathrm{~L}^{1} \mathrm{~T}^{-1}\right]$.
