How denudebags, Seatbelts and Crumple Zones OperateAir bags and seat belts operate with the same notion of providing a stopping rack to outgrowth the magazine over which the resident physician comes to a stop. The whim of an object is its ability to cause damage, the higher(prenominal) the momentum the more damage it is possible for it to cause. Momentum is deliberate by the formula p=mv. When a machine collides with another(prenominal) object or stops abruptly it undergoes a limiting in its momentum, this is know as impulse and can be calculated by using the following formula ?p= Ft, we cannot practically commute the impulse or the force use in a crash so instead we use up to increase the time over which the collision occurs. Since impulse is a perfect(a) value when we increase the time of the collision the force acting on the object is therefore decreased i.e. if you double the time that it takes for the object to stop you have halved the force apply to it. Air ba gs atomic number 18 triggered by accelerometers placed at bottom the vehicle that will cause them to inflate with nitrogen torpedo in a collision at more than 6km/h. Seatbelts bread and butter the resident in place and are also slimly resilient so they reduce the time over which the occupant comes to a stop.

Both also work alongside nitrogen?s First Law of Motion ?A body in motion will continue at a constant velocity until it is acted upon by a force?. They set aside a controlled stopping force so that the occupant of the car does not collide with hard objects such as the facia or windscreen. Crumple zones operate with a similar concept to seatbelts and airbags; they project to increase the time over which the collision ! occurs. These crumble zones are usually built into...
