linear momentum
Mass times velocity
Linear momentum is the product of an object's mass and velocity—a measure of how much force would be required to stop it.
A freight train moving slowly may have the same momentum as a bullet moving fast.
In physics, momentum is conserved: in any closed system, total momentum remains constant.
The collision transferred linear momentum from one billiard ball to another.
The qualifier "linear" distinguishes motion in a straight line from angular momentum, which involves rotation.
