According to Newton's second law, this change in flow direction requires a downward force applied to the air by the airfoil. Source: Internet

According to Newton's third law, the air must then exert an equal and opposite (upward) force on the airfoil, which is the lift. Source: Internet

Air above the airfoil is pushed toward the center of the low-pressure region, and air below the airfoil is pushed outward from the center of the high-pressure region. Source: Internet

A returning boomerang has two or more airfoil wings arranged so that the spinning creates unbalanced aerodynamic forces that curve its path so that it travels in an elliptical path and returns to its point of origin when thrown correctly. Source: Internet

Although this application was abandoned, publicity inspired hobbyists to adapt the flexible-wing airfoil for modern hang gliders. Source: Internet

At higher speeds on powered aircraft, the boundary layer on the airfoil is turbulent and more complex vortex shedding patterns have been observed. Source: Internet
