Question

define Momentum write its SI unit

Answer 1

Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.
it formula = mass × velocity
so it's SI unit is = kg×m/s = kg m/s
Hope this helps u

Answer 2

Answer:

Momentum has its SI unit as $\bold{\frac{\mathrm{kgm}}{\mathrm{s}}}$

Solution:

The momentum is experienced over a moving body. Momentum is a measure of the total quantity of motion experienced by the body which is in motion.

Momentum is thus, a vector quantity which has magnitude as well as direction.

Momentum is measured product of motion and is therefore, derived as the product of mass of the body in motion and the velocity it has attained.

$\text{Momentum} = \text{Mass of body} \times \text{Velocity of body}$

$\text{Momentum} (\mathrm{p})=\text { mass }(\mathrm{m}) \times \text { velocity }(\mathrm{v})$

$\mathrm{p}=\mathrm{m} \times \mathrm{v}$

$\mathrm{p}=[\mathrm{M}] \times\left[\mathrm{LT}^{-1}\right]$

$\mathrm{p}=\left[\mathrm{MLT}^{-1}\right]$

$\mathrm{p}=\frac{\mathrm{kg} \times \mathrm{m}}{\mathrm{s}}$

$\mathrm{p}=\frac{\mathrm{kgm}}{\mathrm{s}}$
