Momentum Calculator

🎱 Momentum & collisions. Use the Momentum formula to find momentum, mass, velocity: pick the value you want, type the others, and the answer updates as you go.

p=mvp = mv
Momentum0.64 kg m/s

Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.

Worked example

Find the momentum when Mass = 0.16 kg, Velocity = 4 m/s.

Using p = mv: Momentum = 0.64 kg m/s.

Frequently asked questions

What is the formula for Momentum?

p = mv.

What do the letters stand for, and what units are used?

Momentum in kg m/s, Mass in kg, Velocity in m/s.

How do you calculate momentum?

Put the values into p = mv. For example, with Mass = 0.16 kg, Velocity = 4 m/s, momentum = 0.64 kg m/s.

Can I solve for a different value?

Yes. In the calculator above, pick the circle next to any value (momentum, mass, velocity) and fill in the others: it rearranges the formula for you.
