NettetSeat belts These are designed to stop a passenger from colliding with the interior of a vehicle by keeping them fixed to their seat in an abrupt stop They are designed to stretch slightly to increase the time for the passenger’s momentum to reach zero and reduce the force on them in a collision Airbags Nettet24. apr. 2024 · Updated April 24, 2024. By Chris Deziel. The second of Newton's three laws of motion tells us that applying a force on an object produces an acceleration proportional to the object's mass. When you're wearing your seat belt, it supplies the force to decelerate you in the event of a crash so that you don't hit the windshield.
NettetIn 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. NettetThe task of the seatbelt is to stop you with the car so that your stopping distance is probably 4 or 5 times greater than if you had no seatbelt. A crash which stops the car …
