Calculate the momentum of a moving object from its mass and velocity.

How It Works

How Momentum Calculator Works

Momentum is simply mass multiplied by velocity — unlike kinetic energy, it scales directly (not squared) with speed, and its direction always matches the direction of motion.

FAQ

Frequently Asked Questions

Why does momentum matter in collisions?
Total momentum in a closed system is conserved before and after a collision, which is the basis for working out post-collision speeds in everything from billiard balls to car crash analysis.
