How do seat belts prevent injury physics?
In 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.
