Why you need to tide seat belt in airplane?

Why you need to tide seat belt in airplane?

Hello friends I think all of you have wondered about you asked to tide your seat belt during the time of takeoff and landing while you are travelling in a plane. And I thank you also want to know why it is not mandatory to were all the time you are travelling, why it is mandatory only in taking off and landing time? Today I am going to discuss this in a scientific way and after that I thing you will sought in with a laugh of understanding. So let’s get started….

Before we started I want to discuss a normal natural phenomenon related to our weight in lift (here lift means while going upwards).

Friends if we define weight we should defined it as Weight is a force experienced by a body as applied by a surface in contact.

If R is the force experienced by a person standing an ground by the surface in contact i.e. ground than the person experience this as his weight.

Mathematically it is written as

                                                          R = -mg

Where m is the mass of the person and g is force of gravity act on him or acceleration due to gravity

Here negative sign is use because both the force is opposite to each other.

Now if we travel upward with an acceleration of “a” and if we calculate it we will get

                                      R= m (g +a)

                                                This means your body weight increases and you will feel yourself heavy.

Now if we travel downward with an acceleration of “a” and again if we calculate we get

                                      R = m (g-a)

                                                          This means your body weight decreases and you will feel yourself lighter than before.

If somehow the value of “a” became equal to “g” than you will got

                                      R = m (g-g)

Which will be equal to zero and my there friend believe me than you fell weightlessness. And this is what the skydiver experienced for a little bit of time.

Now come to the topic again. Friends When our airplane is taking off it accelerate itself and accelerating itself still is got a perfect height to fly. So friend when the plane is accelerating upwards than you are also doing so. Because of this you body weight will start increasing. I think you have experienced that in that time of taking off you are going in and into the seat or it is also feel that the seat is catching you tidily. It is because while you are accelerating upward you are become heavy. But when the plane stops accelerating your body weight comes to its original value. And the real twist is here. Because for the of accelerating you became heavy and you are going in and into the seat and when the plane starts traveling in a constant velocity your body weight became normal and then you can feel that the seat was throwing you out and you may be fall from it. So tiding your seat belt is really important while taking off.

Now in the time of landing you are accelerating downward so your body weight became less and less. And my dear friends in that time you fall from your seat. So tiding seat belt is also necessary while the plane is landing.

But some time seat belt are advice to ware in the time of normal flying because of turbulent and if there is any weather change because you might be hart in that situation.

So friends I think now you understand why we are advice to ware seat belt while travelling in a flight. If you have any suggestion  or question, please write it down in the comment.
