LIft (force)

How many times have we seen a plane flying over us, but do we ever wonder how something so big can fly? Everything depends on the lift of the wing. The key to understand the miracle of flight is Bernoulli’s principle, which describes the behavior of a viscous fluid under the action of the force-weight. One consequence of this is that the pressure that presses under the the wing is greater than the one which is exercised on the top, what determines the force called lift that supports the aircraft in flight.
