relation between air bag and Law of Inertia
Physics and Airbags are related together due to Isaac's laws, however only one of his law related to airbags and it's the 1st law which is Law of Inertia. What is Newton's first law anyway? According to him, the law is, "An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force." What does this means?This means an object will not move and stay still unless a force push or pull it and the same idea goes with a moving as object as it will go at the same speed and direction unless a force stop it.
How does such law related to airbags? Well, since an object will move at the same direction and speed unless something stop it, this means when you are in a crash, your body will be thrown out unless you hit something. In most cases, the driver will hit the steering wheel, the passenger on the front will hit the dashboard, while the other passengers will hit the seats in front of them. This where airbags comes in handy because as soon as the airbags reacted to the force produced from the colision, it will inflate itself, preventing the passengers and driver from hitting anything in front of them.
However, airbags can't work alone as it can always prevent the people from injury like get thrown out from the car or hit by the car. You may ask how such thing may happen? It's actually possible, depending on the scenario, like the speed of the cars, size of vehicles, angle of crash, and etc. For example, if your car get hit from the side, the airbags won't help you since it's in front of you not the side or if you hit a trunk or heavy rock with a very fast speed, you will get thrown out. This is why it's recommended to use seatbelt since it prevent the user to move when a certain amount of force pull the seatbelt.
