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.
