What is the momentum of an object of mass $m$, moving with a velocity $v$?
$(a).\ (mv)^2$
$(b).\ mv^2$
$(c).\ \frac{1}{2}mv^2$
$(d).\ mv$

Option $(d)$ is correct.

Momentum is known as the product of the mass and velocity of a moving object. 

If a body of mass $m$ is moving with velocity $v$, 

then the momentum of the moving body, $P=mv$

Momentum is a vector quantity.

The SI unit of momentum is kilogram-meter per second and is written as kg-m/s.
