WebbSeatbelts safely provide an outside force that can stop or slow down your body when the car stops or slows down airbags work by increasing the time of impact and decreasing the force of impact thus stopping you from getting hurt and being killed. As with any safety system, seat belt performance is dependent on proper use and fit.

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.

WebbIn terms of physics, a seat belt increases the stopping distance of an occupant during a car crash. According to the work-energy principle, this lessens the impact force applied to the occupant. Work = Δ Kinetic Energy (Force) (distance) = Δ½ (mass) (velocity) 2 WebbAccording to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. It is the natural tendency of objects to keep on doing what they are doing. All objects resist changes in their state of motion.

WebbNewton's First Law Newton's First Law states that an object in motion will stay in motion, an object at rest will stay at rest, at a constant velocity, unless an unbalanced force acts upon it.
