Formula
Linear momentum = mass x velocity.
About the Momentum Calculator
Calculate linear momentum and impulse-equivalent quantities from object mass and signed velocity.
How the Momentum Calculator Works
Mass is multiplied by signed velocity so direction is retained; the magnitude and an equivalent impulse in newton-seconds are also reported.
Formula
Linear momentum = mass x velocity.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Mass (required) - enter in kg.
- Signed velocity (required) - enter in m/s.
Results Reported
The result panel reports the final answer and the intermediate quantities needed to check the calculation:
- Signed momentum (kg m/s)
- Momentum magnitude (kg m/s)
- Equivalent impulse (N s)
- Direction relative to positive axis

Accuracy and Limitations
This is classical one-dimensional linear momentum. Vector components, relativistic momentum, variable mass, rotational momentum, and external impulse history are excluded.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
