what is the mathematical equation of correlation for momentum and velocity?

The equation for momentum:

p =mv

In words, momentum is equal to the product of mass and velocity. Is this what you are asking for?

no actually... i think it has to do with another equation with the lorentz factor.

p=mv/sqrt(1-(v/c)2) or more commonly

$$p=mv\gamma$$,

where $$\gamma=\frac{1}{\sqrt{1-(v/c)^{2}}}$$
