1 Answer

Answer :

Flying of airplanes follows the principle of aerodynamics called Bernoulli's principle.  The working behind how a plane flys is really very wonderful when I came to know it was really wonderful it made me fascinating. The science behind is like :  fast-moving air is at lower pressure than slow-moving air, so the pressure above the wing is lower than the pressure below, and this creates the lift that powers the plane upward.  Dynamics of wings movement is very important in the landing and taking off of a plane. Even taking turns in which the dynamics of the tail comes in picture is of very important.  I would like to suggest you that if you want to know more about this deeply and want to visualise it then you can search it on YouTube where with animation they have explained it wonderfully.
