Momentum Calculator
Compute linear momentum (p = m·v) or solve for mass or velocity given the other two values.
Momentum (kg·m/s)
50 kg·m/s
Enter any two of momentum, mass, and velocity, and this calculator solves for the third using p = m × v. Results update live and run entirely in your browser.
How to use
- Select whether to solve for momentum, mass, or velocity.
- Enter the two known values.
- See the calculated result below with correct units.
Frequently asked questions
- What is momentum?
- Momentum is the product of an object's mass and velocity, measured in kg·m/s.
- What units does this calculator use?
- Mass in kilograms (kg), velocity in meters per second (m/s), and momentum in kg·m/s.
- What happens if velocity is zero?
- The tool cannot solve for mass when velocity is zero, since that would require dividing by zero.
