How do seat belts work physics
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. Since the change in K remains the same, an increase in distance decreases the ... WebHow do seat belts work Physics momentum?
