<P> The air flow changes direction as it passes the airfoil and follows a path that is curved downward . According to Newton 's second law , this change in flow direction requires a downward force applied to the air by the airfoil . Then , according to Newton 's third law , the air must exert an upward force on the airfoil . The overall result is that a reaction force , the lift , is generated opposite to the directional change . In the case of an airplane wing , the wing exerts a downward force on the air and the air exerts an upward force on the wing . </P>
