We know, 
Momentum is a product of mass and velocity. 
 
Here in the given equations, 
p -  momentum 
m - mass
u - initial velocity of a body (in case of conservation of linear momentum - 'u' is velocity of a body before collision)
In equation p = mv, 
v - final velocity of a body (in case of conservation of linear momentum - 'v' is velocity of a body after collision)
