Seatbelts reduce the risk of death by car crash by about 50 percent. Without wearing a seatbelt, you would exert through the windshield because of inertia. Inertia is an object’s tendency to keep moving until something else works against the movement. The seatbelt stops the body from exerting forward. It is an opposite force working against the movement of the object. Newton’s first law relates to seatbelts because it states that an object will keep moving in a straight line with constant velocity unless the net force acting on the object is zero. If a car crashes into your car from behind, your body will exert forward until something stops it. If you didn’t wear a seatbelt, the net force that would stop you from continuing to go forward would be the windshield, which could potentially kill you. The seatbelt will stop you sooner because it is a net force acting in the opposite direction of the way you’re moving. Newton’s second law relates to seat belts because this law states that the greater the force, the greater the acceleration and the greater the mass, the less acceleration. When you wear a seatbelt, it stops you from accelerating forward. If you got hit with a car with a large amount of force, you would accelerate faster, but the seatbelt would stop you. When the car is moving at a large speed, the force of the car stopping, makes the person sitting in the passenger seat fly forward. Newton’s third law states that when one object exerts a force on another object, the second object exerts on the first an equal force in the opposite direction. The action forces of a car crash are the cars colliding with each other. When the cars collide, they apply the same amount of force and experience a reaction of equal magnitude. When you get into an accident, the seatbelt you’re wearing hits you with the same force you’re hitting it. This is why the seatbelt can cause potential injuries, but it also depends on your mass and the acceleration of the vehicle.
