WebSep 18, 2024 · Seat belts stop you tumbling around inside the car if there is a collision. Upon sensing a collision the seat belts lock in place. When the car crashes, there is no unbalanced force acting on the person, so they continue forward (Newton’s First Law). The person moves against the seat belt, exerting a force on it. 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. Work = Δ Kinetic Energy (Force) (distance) = Δ½ (mass) (velocity) 2
