Physics Behind Car Crashes

In everyday understanding of car crash collision, there must exist two objects which constitute an event of two or more bodies which exert some force on each other at a relatively period of time. Most of the crashes are under the influence of the magnitude of force which exemplary involves at least two automobile vehicles colliding together. The motion between the two bodies may involve some internal forces and external which combine together to give that impact. During this magnitude interaction their exist some velocity difference which as a result of the impact of the closing speed and the passengers who are in the vehicle as they are still in the same motion.

All mode of crash are accompanied by momentum but what distinguishes the collision is the line of impact which might either be collinear based on the normal surface of the body in contact with. This line of interaction is always between the car force and the passenger and is closely associated with the internal force of motion which act due to impact of newton’s coefficient forces which restitute the line of collision. As a matter of fact as we base on this collision, the body has some speed which has a common cause with the momentum of the other vehicle in close contact. Then when the car collides with a wall which was at stationery, some external force on the car tends to move it hence causing in some deceleration for the car to come to rest and this tends to push the passengers ahead due to this extra force of collision exerted.

In addition, the highest percentage of passengers inside the car might tends to come to deceleration due to that buckled tension. For instance, when one decides to slow down in a traffic, most of the passengers also decelerates. Their comes another instance that the car has maintained a kinetic energy and is moving with a constant speed then the people who are inside the car also enjoys in maintaining the same impact of force. This force to some extend are insignificant as the amount of friction that they exert between the people and the sets might likely cause the car to propel and this leavers the passengers in a projectile motion due to change of acceleration forces. According to some of the collision, they may either be elastic where they do conserve in some momentum and inelastic which does not tempt to conserve the kinetic energy exerted on the car. Moreover, most of the vehicle features in the notion of Isaac newton three types of forces as they apply to the car and the passengers. This three laws step up to explain a body at rest, in acceleration motion and a body moving in a constant speed.

In newton’s first law it elucidate clear that a body which is on continual motion unless one acts upon it to ignite the motion it will remain in that motion. The law conserve that the body will remain in uniform motion unless some force are acted on it which are external ones and cause change in kinetic energy and momentum. This forces asserted to the car will continue moving in the same pace unless the vehicle experiences some external force which might tempt to cause this collision and cause a drag of motion resistance. Newton decide to use this inertial law to give an explanation to some of the tendency with which most of the passengers experience in resist this change of motion when the kinetic energy outweigh potential energy.

In case a certain car collides with another, we have some different forces considerations which are under a highly idealized situation. They may tend to collide with each other while moving with the same speed but precisely in most of the times moving in different directions. From this view it is clear that momentum and conservation must come to rest and this might interfere with the passengers who may have some identical impact. This force of collision arrives us to the second newton law which provides in some equations and quantitative calculation based on ones understanding of the effectiveness of wearing seat belt to prevent in an emergency and reduce deaths. Hence, the law states clearly that relationship between mass, m acceleration a and force f is calculated as follows: F= ma.

Therefore, the greater the mass of the object the more inertial force it will exact on the body. Due to this some unbalanced force tends to be greater and might change the speed and direction of the object which is in motion. Passengers and the car which are on separate force moves in the same direction and same velocity when kinetic energy has not been tampered with. Most of the physicists have the research idea that as particles accelerates under high energy, the speed is lowered and this seems to shatter the atoms which constitute the object. Under that difference, some quantum level of the particle, energy and matter might basically exert some of this Collison no matter the energy exerted to the object. It is clear that most of the car have seat belts which reduces most of those external forces and in spite of that they distribute inertia force across the passenger’s body. Most of the belts acts as unbalanced force as they protect the passengers from their own inertial force. Again, it is clear that as we wind up, the motion exerted is restrained and prevents one from being banged and tossed up when the car launches abrupt in an angle.
