Calculate the momentum of a moving object from its mass and velocity, a key quantity in collisions. Enter mass and velocity to see momentum when you calculate.
Worked example
Example calculated from the starting values. Enter your own values and press Calculate to get your result.
With the default inputs (mass = 80 kg, velocity = 5 m/s), the results are: momentum 400.00 kg·m/s.
Quick reference: mass vs result

| 1,600 | 8,000.00 kg·m/s |
Frequently asked questions
What formula does this calculator use?
Momentum = m × v. Variables: m = mass in kg, v = velocity in m/s.
What do I need to enter?
You need mass (kg), velocity (m/s). Results update as you type.
What is an example result?
With the default inputs (mass = 80 kg, velocity = 5 m/s), the results are: momentum 400.00 kg·m/s.
