Scientific reasoning!!!!!!

On our way to SWEDEN, it took us 61/2 hours to reach Stockholm(capital of Sweden) from Doha and on our way back it took us just 51/2 hours to cover the same distance.

Isn't this something interesting???


This interesting fact is supported by a scientific reason which was brought to our notice by sir Dange and something that facinated all of us.


The reason to it is that on our way from Doha to Stockholm, the aircraft faced headwind as a result of which the groundspeed of the aircraft was lowered as there was an opposing force resisting its own force.

Headwind is a wind that blows against the direction of travel of an object. A headwind reduces the object's speed and increases the time required to reach its destination. Headwinds are commonly measured in relation to the speed of vehicles - commomnly air and watercraft - as well as running events - particularly sprints.

In aeronautics, a headwind is favourable in takeoff and landings. As a result aviators and ait traffic controllers commomly choose to takeoff or land in the direction of a runway that will provide a headwind.



The opposite wind to the headwind is the tailwind that the aircraft experienced on our way from Stockholm to Doha(that is on our way back home) which increased the speed of the aircraft as it blew in the same direction as the aircraft pushing it with a force in the forward direction.

Tailwind is a wind that blows in the direction of travel of an object. A tailwind increases the object's speed and reduces the time required to reach the destination. Tailwinds are commonly measured in relation to the sped of the vehicles - commonly air and windcraft - as well as in running events - particularly sprints.

In aeronautics, a tailwind is unfavourable in takeoff and landings. As a result, aviators and air traffic controllers commonly choose to takeoff or land in the direction of a runway that will provide a headwind.

  1. Dear Urvi

    Glad to have you all back.

    I would just like you all to think about something. Over the next few weeks, until the novelty wears off, there'll be lots of differences that you'll notice between Stockholm and here. Some will be good, and some not so good. it would be interesting if you take the time to put your observations down on this blog for all of us to read.

    Please can you pass this on to the other's in your group

    Thank you, and glad to have you all back again

  2. Dear sir

    Thank you very much and i am extreemly sorry for the late reply. I couldn't visit the blog recently as I got a little bussy with my exams coming up on the 6th of this month.

    I would love to write down all my views regarding the differences we observed. But sir if u grant me the permission to put up a nice blog on the topic mentioned after my exams, I shall surely do so.

    I have already informed all the others from our group regarding your message.

    Once again i an extreemly sorry sir.
