Practical tools for measured work
Momentum calculator
Solve signed one-dimensional momentum, mass or velocity.
Calculate the layout, check the diagram, then print the result for the shop or jobsite.
How it works
Classical linear momentum p = mv. Momentum and velocity carry a sign along your chosen axis. A 2 kg mass moving at −3 m/s has momentum −6 kg·m/s. Solve an inverse relation only when its divisor is nonzero.
Current-input example
The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.
- Solve for
- Momentum
- Mass
- 2 kg
- Signed velocity
- -3 m/s
Primary result: Result: -6 kg·m/s.
Before using the result
- Check the selected mode, units and input values before using the result.
- Read the assumptions and rounding rules; compare the worked example with your intended calculation.
- A numerical result does not supply missing context or change the stated limitations.
Limitations
Mass must be positive. This is one-dimensional classical momentum, not relativistic momentum or a collision-system solver.
