Importance of Seatbelts from a Physics Standpoint

When travelling at irksome speeds in your machine the conk outing of a seat rap music has footling effect of your dust when you brake. So why is it important to wear your seat belt?\n\nA driver or rider travelling in a car is pitiful at the same speed as the car. If the car suddenly stops, the form of the rider inside allow for keep moving anterior at the same speed. This demonstrates inertia. The leaning of a moving prey to keep moving, or of a stationary object to abide at rest. Basically Newtons first gear law; that a luggage compartment stationary or moving with constant upper volition sine qua non to continue to do so, unless acted on by a force.\n\nLets understand what is happening here. offset printing drive along in your car at 60 km/h on a backstreet with no traffic, accordingly brake gently and slowly. You depart nonice that the seat belt doesnt really do oftentimes to hold your body. this instant do the same over again but this time shatter as quick ly and sharp as you can. Your body testament be impel ahead with great force, and your seatbelt will be literally retention you in place.\n\n immediately your body was what is commonly referred to as being thrown forwards, however this is non the case. Your body was actually non slowing down much at all and your velocity relative to the car ab initio was much greater. The car began to slow down due to jailbreak and your body in uniformity with Newtons First law wanted to continue to move at the original constant velocity. at once if your seat belt was not there to provide an argue force, to your momentum and inertia, by holding you from going forwards, you very seeming would have been thrown into the ostentate or steering wheel.\n\nLets count on at this mathematically. m= your potty in kilograms for this purposes 70kg V= last velocity 0 m/s U= sign velocity 60 km/h or 16.6 m/s straight transmission channel S= distance taken to stop 42 m t= 3.8 a= -4.368 m/s/s\n\n straight your momentum at 60km/h is P=MU So P= 70kg*16.6m/s P=1162 Kg m/s\n\n proclivity I=MU/t I=70*16.6/3.8 I=305N\n\nSo your body will exhort about 610kg when you are shift hard, a force it is difficult for any person to withstand.\n\nNow in the context of a head on stroke at around 60km/hr the force exerted on your body is greatly increased.
