A crazy question isn’t it. how can something designed and marketed as a safety measure actually kill us?
Well, the answer might baffle some of us. Let’s use some science facts to answer this question. We are sure you will enjoy what comes up regarding Airbags.
What is an airbag?
Enter into drivers or co-drivers seat of any new car, you would see SRS airbag written on it. What does this SRS mean? well SRS stands for Supplementary Restraint System. That’s what is the technical name of what we call an Airbag.
Notice the word “Supplementary”, this word can itself answer our question. Airbags are meant to be used in tandem with seat belts. Anyone having airbags in the car must use seat belts while driving. Airbags are designed to cushion the residual impact that seat belts cant handle. Using them without seat belts can be fatal. And we will see why?
Airbags are the devices which on cars impact gets deployed hence reducing the force with which we might have hit the steering wheel or the dashboard of the vehicle.
When a vehicle is moving at high speeds then a thing called momentum comes in to play. Its a mix of the speed of the vehicle plus its weight plus passengers and cargo weight. Anybody or object inside the vehicle will be the part of this momentum. Momentum in the world of physics is mass into velocity. In simple Layman terms if you weigh 60kgs and are traveling at a speed of 60 kmph, then the forces acting on you are 60×60=3600 kgs is the momentum. That means if you hit something with these values you are dead.Basically, airbags with seat belts try to prevent that.
