Fluid mechanics is one of the major disciplines of physics applied in the design of airplane wings. Out of the many things considered is the relationship between angle of attack, airspeed, and lift. The angle of attack is measured in degrees between the chord and the direction of flight. Lift is an artificial force generated by the wings and can be manipulated by a pilot. Lift has varying characteristics during different times of the flight for instance during a level cruise it equals weight, its greater than weight during a climb and during descent its less than weight.
