GENERAL KNOWLEDGE

Detailed explanation-1: -Airbags are not supposed to deploy if seat belts are not being worn. This is because they can cause serious injury or even prove fatal in such deployments. This is not a failsafe mechanism though. Sometimes people bypass the system by using plugs for their seat belts to switch off the alarm.

Detailed explanation-2: -They increase the time taken for the vehicle to slow down in an impact (like an airbag). This reduces the force exerted on the passengers. The deformation (crumpling) of the car also absorbs energy from the collision meaning that less energy is transferred to the passengers.

Detailed explanation-3: -There is a connection between seat belts and airbags. The airbag protects your chest, face and head. The seat belt across the torso and shoulder keeps you sitting upright and prevents body movement in case of a crash.

Detailed explanation-4: -During the collision, the rapid change in momentum of the passenger occurs, and the passenger decelerates at a very fast rate; hence seat belts provide time for the momentum to reach zero, which causes the force to reduce. Airbags also provide the same thing, but it also provides the cushion support to the passenger.
