WebAs the head strikes the bag, it forces air out the vents at the back which allows for the head to sink into the pillow of air and increases the time over which the change in momentum of the passenger occurs. The change in momentum is determined by the speed of travel. WebOct 25, 2004 · 2)Seat belt/rod fastened to the car, but made of iron (or some other inflexible material). In this case, you are forced to decelerate to zero as fast as the car does. The rod would slice you through (a BIG force acting on you). Not nice, IMO. The seat belt allows you some longer time than in 2) to decelerate to zero, hence. haxball powtorki

WebSeat belts are worn when travelling in a car. When the car slows down suddenly (decelerates), each person in the car will experience a force exerted by their seat belt. If …

WebSep 1, 2000 · When a car crashes at a high velocity, a very large force is needed to stop the objects inside because the car’s momentum has changed instantly while the passenger’s has not. Thus, the goal of seatbelts and airbag systems is to help stop passengers with as little damage to the passenger as possible. Getting the Timing Right: Crash Sensors

WebIn words, it could be said that the force times the time equals the mass times the change in velocity. In physics, the quantity Force • time is known as impulse.
