Impulse Calculator
Impulse describes the change in momentum associated with a force acting over time.
How to use this calculator
- Enter signed average net force and the non-negative duration in seconds.
- Check the labels and units before using a result outside this page.
- Change one input at a time if you want to compare scenarios.
Formula and method
J = Faverage × Δt
- J = Faverage × Δt
- The calculation requires average force over the specified interval; peak force cannot be substituted without a suitable model.
Worked examples
Worked example
An average net force of 15 N acts for 0.2 seconds.
Impulse = 15 × 0.2 = 3 N·s.
Impulse = 15 × 0.2 = 3 N·s.
