What is linear momentum

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If m is an object's mass and v is its velocity, then the object's momentum p is \mathbf{p} = m \mathbf{v}.

Linear momentum is defined as the product of a system's mass multiplied by its velocity.
