Webb9 maj 2024 · Does a seatbelt prevent whiplash? " Seat belts and airbags are helpful for preventing severe whiplash injuries and to reduce the impact to the spine ," explains Dr. Herkowitz. “Severe impact may cause injury to the neck area, middle, and lower back.” WebbIf a passenger is wearing a seatbelt, their torso is moved rapidly forward with the car, leaving their head behind and making it bend backwards quickly enough to cause injury. This happens because if a mass (the head) is stationary, Newton's First Law states that …

Conversely, if an object is at rest, it will remain at rest until an unbalanced force acts upon it.

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.
