Online Momentum Calculator

Calculate momentum from mass and velocity: p = mv. Enter mass and velocity to get momentum.

Frequently Asked Questions

What is the formula?
Momentum p = mass (m) × velocity (v).
What units?
Use consistent units (e.g. kg and m/s → kg·m/s).
Can mass or velocity be zero?
Yes; then momentum would be zero. No division by zero in this formula.
