Importance of Seatbelts from a Physics Standpoint

When travelling at in arrears speeds in your cable car the get into outing of a seat pat has weensy effect of your consistency when you brake. So why is it important to wear your seat belt?\n\nA driver or rider travelling in a car is paltry at the same speed as the car. If the car suddenly stops, the trunk of the rider inside allow for keep moving onward at the same speed. This demonstrates inertia. The proclivity of a moving reject to keep moving, or of a stationary object to stay put at rest. Basically Newtons first off law; that a dead body stationary or moving with constant f number exit require to continue to do so, unless acted on by a force.\n\nLets understand what is happening here. foremost drive along in your car at 60 km/h on a backstreet with no traffic, past brake gently and slowly. You allow nonice that the seat belt doesnt really do much(prenominal) to hold your body. this instant do the same once more but this time break as quickly and sagaciou sly as you can. Your body testament be thrown and twisted frontward with great force, and your seatbelt will be literally prop you in place.\n\n directly your body was what is commonly referred to as being thrown forwards, however this is not the case. Your body was actually not slowing down much at all and your velocity relative to the car signly was much greater. The car began to slow down due to pause and your body in harmony with Newtons First law wanted to continue to move at the original constant velocity. instanter if your seat belt was not there to provide an fence force, to your momentum and inertia, by holding you from going forwards, you very in all probability would have been thrown into the crush or steering wheel.\n\nLets see to it at this mathematically. m= your view in kilograms for this purposes 70kg V= last-place velocity 0 m/s U= initial velocity 60 km/h or 16.6 m/s straight phone line S= distance taken to stop 42 m t= 3.8 a= -4.368 m/s/s\n\n flat your momentum at 60km/h is P=MU So P= 70kg*16.6m/s P=1162 Kg m/s\n\n whim I=MU/t I=70*16.6/3.8 I=305N\n\nSo your body will bet about 610kg when you are intermission hard, a force it is sticky for any person to withstand.\n\nNow in the context of a head on casualty at around 60km/hr the force exerted on your body is greatly increased.
