It increases the passenger’s stopping time, and this decreases the force.
Explanation: The passenger’s momentum must change to zero (Δp), and impulse J = Favg·Δt = Δp. For the same Δp, a larger Δt gives a smaller average force. An airbag cushions the impact, lengthening the time/distance over which the passenger is stopped and reducing peak force (and pressure).
