Final answer:
By increasing the collision time, the crumple zone reduces the force on the passengers. Crumple zones in cars protect passengers by increasing the collision time and reducing the force on them.
Step-by-step explanation:
The crumple zone in cars is designed to intentionally fold up during a front-end collision in order to protect the passengers. By increasing the collision time, the crumple zone reduces the force on the passengers.
This helps to decrease the chance of injury, as it spreads out the force over a longer period of time. By increasing the collision time, the crumple zone reduces the force on the passengers. Crumple zones in cars protect passengers by increasing the collision time and reducing the force on them.
