velocity of the driver. In addition to decreasing the velocity of the driver, it also lengthens the stopping distance a passenger travels before impacting on another car or some other hard surface. Crumple zones were not invented until nineteen-fifty-three after automobile designers saw that cars were rigid bodies causing most of the force transferred to the occupants rather than being absorbed by the car. This led to many fatal accidents (Raiciu, Tudor). Isaac Newton first and second law can be used in understanding why crumple zones are needed. We know that an object tends to keep moving at same speed and the same direction unless acted upon and that force equals mass multiplied by acceleration. Translate that into an accident and that equals the force experienced by the automobile and passengers of the vehicles decreases if the distance of the vehicle stop increases. There are

We learned earlier that if a passenger was to get into an accident with no seatbelt their bodily harm from the collision becomes greater. To understand how passengers are thrown around we need to remember Newton’s first law; a body in motion will remain in motion until an external force acts on it. Air bags and seat belts lower your chances of dying in an automobile accident by forty-five percent. When an injury occurs from a collision the severity of the injury can be quantified in many different ways. One is using the Gadd Severity Index. This index was developed using human cadavers in real accidents. The basic formula is GSI=a^5/((2*t)), where a is acceleration or decelerating, g is the acceleration of earth’s gravity at 9.8 meters per second squared and t is the time in seconds. A human head can sustain up to one-thousand with no serious injuries as long as the peak value does not last any more than ten to fifteen milliseconds (Townsend,
