Airbags

An airbag is a automobile safety device. It is basically a balloon made of

strong material that inflates very fast upon collision to absorb a persons

momentum. Airbags are typically found in the steering wheel and glove

compartment of a car. There are a few physics principles used in the making

of airbags. Many technologies are used to test airbags. Airbags have become

one of the many safety benefits in the world today.
 
    There are a few physics principles used in the making of airbags. One of

these principles for example is Newton’s first law which is a body in motion

wants to stay in motion. A collision is caused when a moving car suddenly

hits or gets hit by another object. Now even though the car has stopped the

people in the car are gone a keep moving with the same force. Unfortunately t

he people are going to slam there heads in the dash boards and break there  

necks. This is because of the amount force there moving at. What an airbag

does is absorb that force which will just cause a minor injury.
   
      Airbags are tested with many different technologies. It uses a central unit  

to monitor sensors within the vehicle, including accelerometers, impact

sensors, side door pressure sensors, wheel speed sensors, gyroscopes,and

seat occupancy sensors. When the sensor’s threshold has been reached or

exceeded, the central unit will trigger the ignition of a gas generator

propellant which will rapidly inflate the airbag.
    Airbags are a great safety benefit to society. According to accident

research, the airbag has saved over 14,200 lives in the USA to date. In

Germany, the airbag has prevented over 2,500 fatal injuries since 1990.
   
    In conclusion airbags are used to slow down your force in a collision.

Airbags are set off when sensors reach or exceed there threshold. This safety

device is used world wide to save lives prevent injury.
