Air over the upper surface of the airfoil is induced to move faster than that under its lower surface thus, according to Bernoull's principle, creating a region of lower pressure above the airfoil and a net lift on the airfoil.
buoyancy
buoyancy
The buoyant force, according to Archimedes' principle, is what allows objects to float in fluids. This force is equal to the weight of the fluid displaced by the object, pushing it upward and counteracting its weight.
Airplanes are streamlined in order to reduce drag (coefficient of friction). This allows for less resistance, less fuel consumption, and greater speed.
Causality
The faster a fluid travels the less pressure it exerts. Since the fluid (air) is traveling slower beneath the wing than the air going over the top, lift is created.
because airplanes have wings

They reduce engine speed and extend 'flaps' which allows the wing to keep lift at lower speed.
The working principle of the internet is that users can access virtually anything from any location in the world. This allows for nearly infinite possibilities for communication and research.
