Momentum Calculator
📐 Physics of Matter. Use the Momentum formula to find momentum, mass, speed: pick the value you want, type the others, and the answer updates as you go.
Momentum20 kg·m/s
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Momentum | kg·m/s |
| Mass | kg |
| Speed | m/s |
Worked example
Find the momentum when Mass = 2 kg, Speed = 10 m/s.
Using p = mv: Momentum = 20 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, Speed in m/s.
How do you calculate momentum?
Put the values into p = mv. For example, with Mass = 2 kg, Speed = 10 m/s, momentum = 20 kg·m/s.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (momentum, mass, speed) and fill in the others: it rearranges the formula for you.
