An Aerodynamicist`s View of Lift, Bernoulli, and Newton
... Most single-engine Cessna aircraft have used this airfoil since the 1940s, which almost certainly makes it the most widely used airfoil in the world. The equaltime-of-passage picture of lift-producing flow patterns leads to the seemingly logical yet incorrect conclusion that this airfoil could not p ...

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) refers to forces acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag forces depend on velocity.Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow. Even though the ultimate cause of a drag is viscous friction, the turbulent drag is independent of viscosity.Drag forces always decrease fluid velocity relative to the solid object in the fluid's path.
