Seat belts have been a requirement in vehicles for decades. They prevent injuries and reduce fatalities during car crashes that involve collisions while the car is in motion. Which of these concepts explains why seat belts are effective against injuries due to car collisions? Select THREE that apply.
Responses
A Seat belts act as an unbalanced force against a body's inertia.Seat belts act as an unbalanced force against a body's inertia.
B Seat belts prevent collisions between human bodies and the windshield.Seat belts prevent collisions between human bodies and the windshield.
C Seat belts prevent an object in motion from continuing to move forward.Seat belts prevent an object in motion from continuing to move forward.
D Seat belts increase the momentum of the vehicle but not the person within the vehicle.Seat belts increase the momentum of the vehicle but not the person within the vehicle.
E Seat belts prevent an object in a circular motion will continue to move in a circular motion.
The correct answers are A, C, and E.
A - Seat belts act as an unbalanced force against a body's inertia, meaning they provide a force in the opposite direction to the body's natural tendency to keep moving forward. This helps to stop the body's forward motion and prevent injuries.
C - Seat belts prevent an object in motion from continuing to move forward. By restraining the body, seat belts prevent it from being thrown forward in the event of a collision, reducing the risk of injury.
E - Seat belts prevent an object in a circular motion from continuing to move in a circular motion. In a car crash, the occupants of the car can be thrown in various directions. Seat belts help to keep the occupants in their seats and prevent them from being propelled in a circular motion, reducing the risk of injury.
