Without the aerodynamic forces of lift and drag, aircraft would be unable to fly, wind turbines would not spin, and countless other machines that we depend on every day would not work. What, exactly, ...

Even in 1800, it was understood—by at least one person, a certain George Cayley—that two forces, weight and drag, were antagonistic to flight and that there must be two corresponding forces to ...

Aerodynamics explains how airplanes fly through the interplay of four fundamental forces: lift, weight, thrust, and drag. Lift opposes gravity, thrust propels forward, and drag resists motion. Pilots ...
