Final answer:

Seat belts reduce injury by extending the time of impact, decreasing the force experienced by passengers during a collision.


Explanation:

Seat belts prevent injury by spreading the force of a collision over a longer time, reducing the force experienced by the passengers. This happens because the seat belt extends during a collision, increasing the time over which the force acts. By doing so, the average decelerating force experienced by the passengers is decreased, enhancing their safety.
