Question

To ensure that a vehicle crash is inelastic, vehicle safety designers add crumple zones to vehicles. A crumple zone is a part of a vehicle designed to crumple easily in a crash. Use Newton’s second law to explain why crumple zones reduce the force in a collision.

Answer 1

Answer:

With crumple zones at the front and back of most cars, they absorb much of the energy (and force) in a crash by folding in on itself much like an accordion. This delays the time to impact. As Newton's second law explains force = Mass x Acceleration this delay reduces the force that drivers and passengers feel in a crash.
