Statistics How many cars and trucks have air bags for the driver? 63.6% or 137 million out of 215 million cars and trucks have air bags for driver. How many cars and trucks have passenger air bags? 115 million cars have passenger air bags,that’s about 53.8% of cars and trucks. Since we have had air bags, there have been over 10,700 lives saved from airbags. Airbags reduce head injuries from car crashes about 25%. Most of the people that have died from airbags either weren't wearing a seatbelt, were wearing a seatbelt incorrectly or were too young to sit in the front seat with air bags. More than 50% of people killed from air bags we women because men are usually bigger

History Air bags we first made in an airplane during World War 2. Air bags were put into cars during the 1980s. Since 1998, new cars could not be sold unless they had airbags. By 1999 new pick-up trucks needed air bags to be sold.

How Airbags Make You Safer and Science Behind Airbags

When you crash your air bags go off. They blow up with air and protect you from crashing into your windshield. If it weren’t for the first law of motion then we wouldn’t really need airbags. We use airbags to prevent ourselves from hitting a hard object. The first law says that an object in motion stays in motion at a constant speed in a straight line. Well if there wasn’t an airbag when you crashed you would be in motion and you would stay in motion at a constant speed and in a straight line until you hit the windshield. That would slow you down and the road would stop you. Airbags make it so you don’t get hurt as easily and they have saved many lives. When a person keeps gaining momentum after they crash the only way they can stop is by getting pushed or pulled by a force. The more speed there is the more momentum a person has so there needs to be more force applied to stop the person. The third law of motion says in a brief way, if one object exerts force on another object they exert the same amount of force on each other. If you hit the ground going 60 mph then the ground will exert the same amount of force on you than you exert on it. If you have airbags then you really wouldn’t have to worry about crashing threw a windshield and hitting the ground very hard.

The reason why you crash through the windshield is because when driving car and you slam on your brakes the car stops because of the brakes but nothing is there to stop you. When the car stops you’re still moving as fast as the car was moving before it slammed on it brakes. Airbags and seatbelts both help you stay safe when you driving in a car and you crash. Without either one of them there would be many more deaths and cars would be a lot more dangerous. Airbags and seatbelts both stop you so you can’t get hurt.
