How does an airbag save your life physics?

Air bags are used in motor vehicles because they are able to reduce the effect of the force experienced by a person during an accident. Air bags extend the time required to stop the momentum of the driver and passenger. During a collision, the motion of the driver and passenger carries them towards the windshield.

How do airbags in cars save human life?

Airbags provide a cushion from the impact of a car’s hard interior surfaces to reduce death and injury. Driver airbags have reduced driver deaths by about 14 percent, and passenger airbags have reduced deaths by 11 percent. Airbags and seat belts are more effective together in keeping occupants safe.

How do seatbelts and airbags save lives physics?

While the driver with an airbag may experience the same average impact force as the driver with a good seatbelt, the airbag exerts an equal pressure on all points in contact with it according to Pascal’s principle. The same force is distributed over a larger area, reducing the maximum pressure on the body.

How important is an airbag to drivers or passengers safety?

According to the Insurance Institute for Highway Safety (IIHS), newer vehicles with airbags are reducing driver deaths in frontal crashes by 29 percent. Passenger airbags have decreased the fatality count of passengers over age 13 by about 32 percent. Between 1987 and 2017, 50,457 lives were saved by frontal airbags.
