dont remember equations exactly, but it has to do with impulse, I. If you can spread the impact over a longer period of time, or distance, you reduce the damage. so wearing a seatbelt help because without it, you are smashing your body into a solid object in a fraction of a second...and that hurts...

Newton's 1st law of motion states objects in motion tend to stay in motion in a straight line. This is inertia. If you are in a car traaveling at 60 mph you are moving at 60mph.If the car stops suddenly, your body will keep going forward unless your seat belt keeps you from going through the wind shield. The 2nd law is force= mass times acceleration. You would use this to find out how to accelerate the car. Force is measured in newtons in the metric system. 3rd law says every force has an equal and opposite force. If you blow up a balloon and let it go, the balloon rushes forward as the air rushes out.(jet propulsion) This is used in a car when the tires push on the road and the car goes forward.

If you are in the car while it is driving you will have the same speed like the car. So if you brake suddenly, you will have the same speed while the car car will stop. In order to increase the safety, you use safety bell to make you like a part of the car body so you will lose the speed as the car do.
You can buy a car with air bag.

Wow, is Aline in your class?
You two should work on this together.
