Which physical quantity is represented by the ratio of momentum and velocity of the body?

Explanation

If the mass of an object is m and its velocity is v, then its momentum is $\vec{P} = M \times \vec{V}$ So, the ratio of momentum to velocity is: $$ \frac{\vec{P}}{\vec{V}} = \frac{M\vec{V}}{\vec{V}} = m $$
