When there is a car crash, the car, its contents and the passengers deceleraterapidly. They experience great forcesbecause of the change in momentumwhich can cause injuries.
seat belts
air bags
crumple zones
These features reduce injuries to the people in the car by absorbing energy from the impact. They increase the time taken for the change in momentum on the occupants' bodies, and so reduce the forces involved and any subsequent injuries.
