Final answer:
Seat belts protect passengers by exerting a force to slow them down gradually during sudden stops or accidents.
Explanation:
Seat belts are designed to protect passengers in cars during sudden stops or accidents by exerting a force that slows them down gradually.
When a car suddenly stops, Newton's first law states that the passengers will continue moving forward at the same speed unless acted upon by a force, which is where seat belts come into play to provide that necessary force.
Seat belts help distribute the deceleration force over a longer period, reducing the risk of injury by decreasing the impact force experienced by the driver and passengers.
