WebbAdding reaction distance to braking distance, the stopping distance for Car 1 is 27.1 + 16.3 = 43.4 metres. For Car 2, stopping distance is 25 + 13.9 = 38.9 metres. Car 1 therefore takes 4.5 more metres to stop than Car 2, a 12 per cent increase. We can now see why Car 1 is more likely than Car 2 to hit Sam.

Years after the Model T was assembled, the seat belt was implemented in some cars as the only form of restraint. People were reluctant to use the belts at first, claiming that they were uncomfortable and restricted their movement. Webb1. Different materials for seat belts means cars can be cheaper or more expensive This will affect the economy since if cheaper or more expensive materials are being used to make seat belts, then the car that used the materials will be either cheaper or more expensive.

Webb9 maj 2024 · When the car crashes, there is no unbalanced force acting on the person, so they continue forward (Newton's First Law).

WebbA seatbelt's job is to spread the stopping force across sturdier parts of your body in order to minimize damage. A typical seatbelt consists of a lap belt, which rests over your pelvis, and a shoulder belt, which extends across your chest. The two belt sections are tightly secured to the frame of the car in order to hold passengers in their seats. WebbAir bags do not just reduce the impact force by elongating the time factor, they also spread the impact over a larger contact area. By doing this, the force is not all concentrated in one small area of your body and the pressure on your body is reduced. This in turn will cause the seriousness your injuries to be reduced.
