Impulse Calculator
Find a component of impulse and momentum change from average net force and interaction duration.
Formula
J = Faverage Δt = Δp.
Interaction duration: 0.2 s · Impulse / momentum change ≈ (10)×(0.2 s)
How to use
- Enter signed average net force.
- Enter the interaction duration.
- Read impulse, equal to momentum change.
Examples
- An average force of −2 kN for 5 ms gives −10 N·s.
Frequently asked questions
Can force vary during impact?
Yes. Enter its average over the interval, not the peak.
What is the unit?
N·s, equivalent to kg·m/s.
Does impulse give final momentum?
It gives the change; add it to initial momentum along the same axis.
