Physics touches every part of your life. In this video, you get to examine how physics determines the dynamics of a car crash. Form fuel consumption, to how cars are designed to fold on impact, vehicles deal with a lot of physics components. Since most people don’t like long nozzles on cars to dissipate the force of a crash, the front ends are designed to dissipate as much energy as possible on impact. Cars could be manufactured more rigidly, but the results would be that such a sudden stop would rearrange your brain and organs—rather quickly.
While crumbling in a crash, cars need to maintain a certain amount of resistant force. Over half of the crumbling absorption is maintained by a pair of steel rails that connect the front bumper to the vehicle’s chassis. The rest of the impact is absorbed the vehicle’s frame. So, the next time you see a vehicle crumple in an accident, you’ll have a good reason as to why.
