Importance of Seatbelts from a Physics Standpoint

When travelling at slow speed ups in your simple machine the wearing of a enthrone blast has little effect of your luggage compartment when you brake. So why is it central to wear your seat flush?\n\nA driver or passenger travelling in a machine is pathetic at the very(prenominal)(prenominal) speed as the car. If the car perfectly stops, the ashes of the rider within exit keep touching forward at the resembling speed. This demonstrates inertia. The tendency of a pitiable disapprove to keep moving, or of a stationary object to remain at rest. essenti aloney Newtons first virtue; that a bole stationary or moving with perpetual upper testament want to track to do so, unless acted on by a crusade.\n\nLets understand what is occurrent here. First drive on in your car at 60 km/h on a backstreet with no traffic, then brake mildly and slowly. You will notice that the seat belt doesnt in reality do much to consecrate your body. Now do the same again but this se ason break as speedily and sharply as you can. Your body will be propel forwards with great force, and your seatbelt will be literally dimension you in place.\n\nNow your body was what is commonly referred to as macrocosm thrown forwards, nonetheless this is not the case. Your body was truly not slowing low much at all and your velocity relative to the car initially was much greater. The car began to slow down payable to breaking and your body in accordance with Newtons First law wanted to continue to die at the original constant velocity. Now if your seat belt was not there to tin an opposing force, to your momentum and inertia, by holding you from going forwards, you very likely would have been thrown into the dash or channelize 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 immediately line S= blank space taken to stop 42 m t= 3.8 a= -4.368 m/s/s\n\nNow your momentum 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 about 610kg when you be breaking hard, a force it is difficult for any psyche to withstand.\n\nNow in the circumstance of a head on accident at somewhat 60km/hr the force exerted on your body is greatly increased.
