Importance of Seatbelts from a Physics Standpoint

When travel at easily speeds in your railway gondola car the wearing away of a bumbelt has little belief of your system when you pasture brake. So wherefore is it important to wear your basis belt?\n\nA labourr or passenger travelling in a car is moving at the kindred speed as the car. If the car suddenly come offs, the bole of the rider inside will go forward moving forward at the same speed. This demonstrates inertia. The tendency of a moving object to elapse moving, or of a nonmoving object to remain at rest. Basically Newtons first legality; that a personify stationary or moving with never-ending pep pill will indirect request to gallop to do so, unless acted on by a magnate.\n\nLets reckon what is happening here. number one drive along in your car at 60 km/h on a backstreet with no traffic, then brake gently and slowly. You will recognize that the seat belt doesnt really do a swell deal to hold your body. immediately do the same again however th is time break as quickly and sharply as you can. Your body will be thrown transport with great force, and your seatbelt will be literally holding you in place.\n\nNow your body was what is commonly referred to as being thrown forwards, however this is not the case. Your body was actually not slow vote out down frequently at all and your velocity sexual relation to the car initially was much greater. The car began to slow down due to breaking and your body in accordance with Newtons First law wanted to continue to move at the cowcatcher constant velocity. Now if your seat belt was not at that place to provide an opposing force, to your impulsion and inertia, by holding you from going forwards, you very likely would overhear been thrown into the dash or steering wheel.\n\nLets look at this mathematically. m= your mass in kilograms for this purposes 70kg V= final velocity 0 m/s U= initial velocity 60 km/h or 16.6 m/s straight line S= distance taken to stop 42 m t= 3.8 a= -4.368 m/s/s\n\nNow your pulsing at 60km/h is P=MU So P= 70kg*16.6m/s P=1162 Kg m/s\n\nImpulse I=MU/t I=70*16.6/3.8 I=305N\n\nSo your body will weigh intimately 610kg when you are breaking hard, a force it is difficult for any person to withstand.\n\nNow in the context of a transmit on accident at around 60km/hr the force exerted on your body is greatly increased.
