How Cars Protect People in a Crash: The Physics of Vehicle Safety (Parent Q&A)
This guide explains how physics and engineering can reduce harm when a vehicle collides. It covers crumple zones, the passenger safety cell, seat belts, pretensioners, load limiters, airbags and head restraints. It also explains momentum, kinetic energy, inertia, force, impulse and stopping time, and shows what crash tests and Euro NCAP ratings can and cannot tell us.
