How it works
Use classical linear momentum with the units stated beside the fields. This form solves for mass; enter the known quantities in Momentum magnitude, Speed.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Momentum magnitude | 26.25 kg·m/s | Formula symbol: p. Required unit: kg·m/s. Must be greater than zero. |
| Speed | 3.75 m/s | Formula symbol: v. Required unit: m/s. Must be greater than zero. |

Reading the result
The result solves for mass from the entered quantities. Check the result unit and the formula conditions before using it.
Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the mass result?
This model uses positive magnitudes. Use momentum and speed magnitudes on one axis; direction and relativistic corrections are excluded.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
