What Is the Formula for Momentum?

Momentum is equal to the mass of an object multiplied by its velocity. The final unit of momentum is equal to the kilogram-meter per second.

Momentum, a vector quantity, is a measurement of an object's force of motion. It is a term used in physics to describe the amount of motion that an object has. It is completely dependent on an object's mass and velocity; therefore it may change as the object's velocity changes. Since the quantity is also a vector quantity, it describes an object's direction of motion, and the object's direction must be reported in every momentum equation.
