How it works
Use average force and impulse with the units stated beside the fields. This form solves for force magnitude; enter the known quantities in Impulse magnitude, Time interval.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Impulse magnitude | 27 N·s | Formula symbol: J. Required unit: N·s. Must be greater than zero. |
| Time interval | 2.25 s | Formula symbol: t. Required unit: s. Must be greater than zero. |

Reading the result
The result solves for force magnitude 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 force magnitude result?
This model uses positive magnitudes. Force is the average over the interval. Impulse is the magnitude of the momentum change on that axis.
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.
