Impulse & Momentum Calculator

Science & Engineering

Ft = mΔv · crash cushioning · airbag principle

Quick Answer

Impulse & Momentum Calculator: Ft = mΔv · crash cushioning · airbag principle. Impulse & Momentum Calculator uses standard science & engineering formulas to compute accurate results instantly.

How it works

  1. 1Impulse-momentum: F·t=mΔv
  2. 2Enter mass, initial/final velocity and duration
  3. 3Longer duration → smaller average force for the same Δp
  4. 4Airbags, crash cushions and bending knees all stretch time to cut force

Average force960N
Impulse：480 N·s
Equivalent acceleration：1.63 g
For the same Δp, force scales inversely with duration: a 0.01 s hard hit vs a 0.1 s airbag cushion differs 10×. Landing mats, athletic technique and car crumple zones all exploit this. Values are time-averaged — peak force can be several times higher. Sign indicates direction (F<0 = braking).
