Question

Modern vehicles are designed ________ in a crash to absorb kinetic energy?

Answer 1

Car components are designed to crumple to increase the time of impact in a crash, reducing the force on passengers and thereby decreasing the likelihood of injury.

Step-by-step explanation:

Modern vehicles are designed to crumple in a crash to absorb kinetic energy. This is due to the physics principle of impulse, which is the product of the net force applied on an object and the time over which it acts (Fnet Δt). The main purpose of a car crumpling is to extend the duration of the impact, which in turn, reduces the force exerted on the passengers during a collision, thereby reducing injuries. For example, the plastic components and design of a car allow it to crumple upon impact, providing a longer time to reduce speed and consequently lessening the force that passengers experience. Similarly, features like airbags and dashboard padding work to cushion the occupants and prolong the collision time.

Answer 2

The answer would be crush. The impression is to extend the time that the collision happens - this decreases the determined force that you feel. Supposedly, if a car can double the distance of a smash, then the supreme force that people would knowledge would also be half. So by letting as much of the car to crush as likely, while still defending the passengers, sorts the cars that much not dangerous.
