Impulse Calculator
Impulse from a force over a time, or from the change in a mass’s velocity.

How it's calculated
J = F × Δt = m × (v − u)
Impulse is a force multiplied by how long it acts, and it equals the change in momentum it causes. That is why airbags and crumple zones save lives: they stretch the stopping time, so the same change in momentum needs a smaller force. The force here is the average over the contact.
