Cars are designed with several safety features to protect passengers during a collision.
Apart from airbags, name two safety features that reduce the risk of serious injury in a car crash.
Using the concepts of momentum, time, and force, explain how an airbag reduces the risk of serious injury to a passenger during a collision.
Suggest why an airbag is designed to deflate slightly as the passenger's head makes contact with it, rather than remaining fully inflated and completely rigid.
In a safety crash-test, a car collides with a solid concrete wall and comes to a complete stop. State what happens to the momentum of the car during the crash.
