WebAir bags do not just reduce the impact force by elongating the time factor, they also spread the impact over a larger contact area. By doing this, the force is not all concentrated in … WebIn terms of physics, a seat belt increases the stopping distance of an occupant during a car crash. According to the work-energy principle, this lessens the impact force applied to the occupant. Since the change in K remains the same, an increase in distance decreases the force acted on the occupant of the vehicle.
