If you are in a car crash
If you are in a car crash and your air bags deploy, you are less likely to suffer damaging injuries due to the sudden change of momentum. This is because the time over which a force is exerted is lengthened, thus reducing the force. However, the produce of force by time remains constant. The amount of force multiplied by the time over which the force is exerted is, for ten points, this physical quantity which is equal to the change in momentum.
