Is velocity related to momentum

Yes

momentum=mass x velocity

or you could rearrange the formula to find velocity = momentum/mass (you get this by dividing both sides in the original equation by mass)

you could also get that mass = momentum/velocity (you get this by rearranging both sides of the original equation by velocity)

Yes momentum is expressed as mass * velocity:

p = m * v

p: momentum

m: mass

v: velocity
