How to calculate momentum
This calculator finds linear momentum from mass and velocity — a fundamental quantity in mechanics representing an object's 'quantity of motion.'
How the calculation works
Momentum = Mass × Velocity.
Example
A 1,200 kg car moving at 20 m/s: 1,200×20 = 24,000 kg·m/s.
Frequently asked questions

Pro Tips for Momentum
- Momentum is conserved in closed systems (like collisions) — total momentum before an event equals total momentum after, a principle widely used in physics problem-solving.
- Momentum is a vector quantity, meaning direction matters — this calculates magnitude, assuming direction is accounted for separately.
Common Momentum Mistakes to Avoid
- Treating momentum as purely scalar when analyzing a collision or interaction involving multiple objects moving in different directions.
