Impulse
Calculate momentum change from a constant or average force.
Your numbers
Impulse
Idealized classical model in SI units. Check sign conventions and assumptions; not a certified engineering design calculation.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use J = FΔt. F is average signed force in N and Δt is duration in s. Impulse J has units N·s and equals the modeled signed change in momentum.
Calculate momentum change from a constant or average force.
Worked example
- Average signed force (N)
- 20
- Duration (s)
- 3
- Impulse
- 60 N·s
Scope and limitations
Idealized classical model in SI units. Check sign conventions and assumptions; not a certified engineering design calculation.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
