Lift Force

Wings are the one of the most fundamental conditions for flying of an airplanem which is related to the lift force acting on the airplane. The wings are made with streamlined shape of convex upper part like the wings of birds in order to get lift forces that make the airplane fly. The lift force is generated when the speed of the air flowing through the upper portion of the wing is greater than that of the air flowing under the wing since the pressur on the upper part becomes smaller and make the air plane float upward.
