Question

Which car safety features absorb kinetic energy?

A. Seat belts and air bags

B. Seat belts and crumple zones

C. Seat belts, crumple zones and air bags

Answer 1

C

Step-by-step explanation:

Seat belts absorb kinetic energy when a car crashes because it pulls you back from falling forward given the kinetic energy (and momentum) you had before the crash.

Air bags absorb kinetic energy when a car crashes because it pushes you back from falling forward given the kinetic energy (and momentum) you had before the crash.

Crumple zones absorb kinetic energy when a car crashes because it provides a cushion when the cars crash. Kind of like dropping your phone into a pillow.

I hope this helps! :)
