WebSep 28, 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. WebSep 20, 2024 · Crumple zones are sections in cars that are designed to crumple up when the car encounters a collision. Crumple zones minimize the effect of the force in an automobile collision in two ways. By crumpling, the car is less likely to rebound upon impact, thus minimizing the momentum change and the impulse. green bug all natural

WebJun 6, 2007 · Isaac Newton's second law of motion is F = ma where F is the force, m is the mass, and a is the acceleration of an object. Acceleration is just the change in velocity over time. a = Δv/Δt where Δv is the change in velocity and Δt is the change in time. So we can rewrite the second law as: F = m (Δv/Δt) flower thank you emoji
