WebAir bags do not just reduce the impact force by elongating the time factor, they also spread the impact over a larger contact area. By doing this, the force is not all concentrated in one small area of your body and the pressure on your body is reduced. This in turn will cause the seriousness your injuries to be reduced.

WebIn an automobile, your body mass is attached to the vehicle's mass via the seat belt; when the vehicle speeds up or slows down, so do you. The first law of motion would apply to your body regardless of the car's direction if you were not wearing a seatbelt. Without a seatbelt, a passenger in a car that has been traveling at a constant speed (as would happen in an … WebThe use of the seat belt assures that the forces necessary for accelerated and decelerated motion exist. Yet, if the seat belt is not used, the passengers are more likely to maintain its state of motion. The animation below depicts this scenario.

WebThe main vehicle safety features are crumple zones , seat belts and airbags. For a given force upon impact, these absorb the energy from the impact and increase the time over which the force takes place. This, in turn, increases the time taken for the change in momentum of the passenger and the vehicle to come to rest. WebThe task of the seatbelt is to stop you with the car so that your stopping distance is probably 4 or 5 times greater than if you had no seatbelt. A crash which stops the car and driver must take away all its kinetic energy, and …

WebA NHTSA study of lives saved by vehicle technologies found that, between 1960 and 2012, seat belts saved more lives—329,715, to be exact—than all other vehicle technologies combined, including air bags, energy-absorbing steering assemblies, and electronic stability control.
