It is a measure that is closely related to how much an object weighs. A moving object also has velocity speed focused on a specific direction. When an object has both mass and velocity, it also has kinetic energy. The great the mass and velocity of an object, the great the amount of kinetic energy it has. That does not become a problem until the object stops moving, either because you want to stop or because it has collided with an object. In either case, the kinetic energy that has been built up needs to go somewhere, it does not simply disappear. So, the faster you are moving, the more difficult it is to stop and the more damage that is done to the vehicle. Most cars are now designed to absorb much of this energy during a collision.

While this reduces some of the danger, it does not account for the fact that the driver and passengers are also objects that have their own mass and during the stopping motion of a vehicle, also have their own velocity. Before airbags, the only things stopping the driver and passengers from being carried forward with continuing momentum were their seat belts.Īirbags work by inflating as soon as the vehicle starts to slow down as the result of an accident. They then begin to deflate as soon as the driver or passenger’s head makes contact with them. If the airbag was not designed to deflate, then it would not solve the problem of the sudden backward movement of the head and neck, as your head would simply bounce off it.Īll of this is possible because of a range of sensors and a small explosion.
The airbag includes an accelerometer that detects changes in speed. If it detects deceleration above a preset speed, which is greater than normal braking speeds, it triggers the airbag circuit.
