Run into a wall with a 2X4 in front of you and a pillow. Tell mew which one absorbs more impact.Nostradamus'omh » 05 Nov 2023, 11:15 am » wrote: ↑ one can have rigid bumpers on crumple zone cars.
Crumple zones don't crumble on impacts less than 5 miles per hour and rigid bumpers are designed to lift taller objects/people that get hit over the car, not underneath it.
Crumple zone cars reduce the trama of second impact of passengers slamming into dashboards and things in front of them inside the car. Kind of why it isn't smart to stack things in the rear window ledge as they tend to fly forward at the speed of the impact.
Mass times motion increases the force of impact. that physics of things in motion different from stationary or potential energy not released.
