WebThe seatbelt stretching increases the time over which your momentum is changed, thereby decreasing the force experienced by your body. Remember: change in momentum = time … WebDuring normal circumstances, you can move easily with your seatbelts on but when the collision occurs, the retractor mechanism tightens up in order to help the drivers stay in place. However, it also loosens up a little allowing the force to spread over a period of time, causing less damage. opening ceremony boots sale https://plantanal.com

http://hyperphysics.phy-astr.gsu.edu/hbase/seatb.html 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.
