Physics Tool
Impulse Calculator
Calculate the change in momentum (Impulse) resulting from a force applied over time.
Total Impulse (J)
50.00 N·s
Σ The Formula
J = F × Δt
Real World Examples
Tennis Strike
A racket hit applying 200N for 0.05s creates an impulse of 10 N·s.
Car Crash
Crumple zones increase Δt, reducing the average force for the same required impulse.
# About This Calculator
Impulse (J) is a vector quantity that describes the effect of a force acting on an object over time. It is exactly equal to the object's change in linear momentum.
A large force acting for a short time can produce the same change in momentum as a small force acting for a long time.
How To Use
- Enter the **Average Force** (F) in Newtons.
- Enter the **Time Duration** (Δt) in seconds that the force was applied.
- The **Impulse** (J) is calculated in Newton-seconds (N·s).
