Airbags-Science Life Savers
Airbags are safety devices designed to protect vehicle occupants during collisions by reducing the impact forces exerted on their bodies. The fundamental principle behind airbags is the concept of rapid inflation and deflation. When a collision occurs, sensors in the vehicle detect the sudden deceleration and send a signal to the airbag control unit. The control unit then triggers the inflation system.
The inflation system of an airbag consists of a solid-state propellant, typically sodium azide, and a mixture of other chemicals. Upon activation, an electric current passes through the propellant, causing it to rapidly decompose and release nitrogen gas. This gas inflates the airbag in milliseconds, allowing it to cushion the vehicle occupant's forward motion and prevent direct contact with hard surfaces, such as the steering wheel or dashboard. The airbag deflates quickly after inflation to allow the occupant to exit the vehicle safely. The entire process occurs in a fraction of a second, providing a protective barrier and reducing the risk of severe injuries, particularly head and chest injuries, during a collision.
VII. Reading & Evidence Questions:
13. Using the text above, how does an airbag work and why does it have to work so quickly? Type Answer HERE: the text says that a airbag works by rapidly inflating and deflating to cushion the vehicle occupants' forward motion during a collision and thats why it works so quickly (information from the text
14. How does inertia play a role during a car accident, and what tools are in place to keep us safe?
Type Answer HERE:
Inertia was in the role during a car accident because objects in motion was to stay in motion
