Crumple Zones design and function
The crumple zone is the front and the rear of a motor vehicle that is designed to crumple without difficulty and to absorb the force of the impact in a crash. Crumple zones are also known as crush zones and they absorb energy in a crash so that it doesn’t transmit to the occupants as much. The zones are now made in cars to prevent death for occupants or serious injuries when in a crash. The front of the vehicle works as a cushion to slow down time so that the vehicle can stop completely and that less forced is applied to the occupants. It reduces injuries and deaths around the world.

When a force is given to an object that can move or is moving, it changes the momentum. If the change in the momentum is faster, the force involved is greater. Momentum is calculated so that mass multiplied by velocity equals to momentum. If a car is driving at a fast speed, the more force and energy it contains. Safety features of a car are put in place so that they protect the occupants’ if a crash were to occur.
Isaac Newton’s Laws of Motion
Isaac Newton was an English physicist, philosopher, scientist and mathematician. He was famous for the law of gravitation in the 17th century, and he also created the Laws of Motion. He wrote and published the physic’s most influential book called Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy).
Isaac Newton’s Laws of Motion explain the reasons as to why accidents occur in vehicle crashes and why they can cause so many deaths around the world. These laws helped prevent deaths and being seriously injured from the impacts of the crashes and many car models now have special safety features added to protect the …show more content…
It was created so that it would reduce damage in a motor vehicle collision. Crash attenuators are designed to absorb energy from the crash of the vehicle and to redirect a vehicle away from something dangerous or to keep cars on the road. Crash attenuators are usually placed near freeways, bridges, race tracks and temporary versions of crash attenuators can be placed on the road near construction projects to keep vehicles out of the way. There are three different ways that can drain out the kinetic energy from the impact, momentum transfer, material deformation and friction. Momentum transfer is when there are rows of barrels filled with water or sand. These were the early models of crash attenuators made to prevent deaths. Material deformation is made out of crushable materials, like the materials used in crumple zones, which absorbs energy from the impact. Crash attenuators can also be made out of corrugated steel that gets flattened when a vehicle crashed against it. Friction converts kinetic energy into heat by forcing a steel cable or strip through a tube that’s on an angle. Tensile steel is the main material to form an impact attenuator, which protects occupants’ when in a crash. Vehicles with crumple zones often hit these barriers and come out with minor injuries because the crumple zone and the crash attenuators absorbs the energy so that less force is applied to the
