Formula used
J = F × Δt = Δp
What you'll need
- Force (N) (e.g. 500)
- Time interval (s) (e.g. 0.1)
What you'll get
- Impulse (N·s)
- Change in Momentum (kg·m/s)
Formula
J = F × Δt = Δp

Frequently Asked Questions
Why are airbags useful? +
They increase the time over which your body decelerates. Same impulse (Δp), spread over more time, means lower peak force. Lower force = less injury.
