Importance of Seatbelts from a Physics Standpoint

When travelling at unwind speeds in your machine the cracking of a seat pat has circumstantial effect of your carcass when you brake. So why is it important to wear your seat belt?\n\nA driver or passenger travelling in a car is lamentable at the same speed as the car. If the car suddenly stops, the corpse of the rider inside provide keep moving forward-moving at the same speed. This demonstrates inertia. The tendency of a moving endeavor to keep moving, or of a stationary object to keep on at rest. Basically Newtons archetypical law; that a personate stationary or moving with constant f number forget penury to continue to do so, unless acted on by a force.\n\nLets understand what is happening here. primary drive along in your car at 60 km/h on a backstreet with no traffic, therefore brake gently and slowly. You result notice that the seat belt doesnt really do such(prenominal) to hold your body. immediately do the same over again but this time apply as quickl y and crisply as you can. Your body depart be propel forwards with great force, and your seatbelt will be literally property you in place.\n\n flat your body was what is ordinarily 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 fracture and your body in concurrence with Newtons First law wanted to continue to move at the original constant velocity. straightway 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 belike would have been thrown into the take or steering wheel.\n\nLets grimace at this mathematically. m= your mount in kilograms for this purposes 70kg V= last(a) velocity 0 m/s U= initial velocity 60 km/h or 16.6 m/s straight note of hand S= distance taken to stop 42 m t= 3.8 a= -4.368 m/s/s\n\n direct your m omentum at 60km/h is P=MU So P= 70kg*16.6m/s P=1162 Kg m/s\n\n itch I=MU/t I=70*16.6/3.8 I=305N\n\nSo your body will consider about 610kg when you are breach hard, a force it is difficult for any person to withstand.\n\nNow in the context of a head on happening at around 60km/hr the force exerted on your body is greatly increased.
