Air bags increase the time the force is applied and decrease the force, so the result is a lesser force for a longer duration.
they relate to the theory behind Momentum and Impulse
Impulse-momentum theorem
change in momentum
An impulse is a change in momentum.
change in momentum
change in momentum
Impulse-momentum theorem
impulse = change in momentum so, no
Impulse-momentum theorem
Impulse is integral of linear momentum with respect to time, and in limits when that momentum was transferred.
The units for impulse are kg.m/s. This is because impulse= (final momentum) -(initial momentum) and the units for momentum are kg.m/s.
impulse (force x time) is equal to momentum (mass x velocity); Ft=mv
