Aerodynamic lift and drag and the theory of flight the wings of birds were the original inspiration for the design of aerofoils however it was not until 1799 that engineer george cayley carried out the first methodical study of the performance of aerofoils his publication on aerial navigation in 1810 marked the beginning of the science of aerodynamics.

Hydrodynamics general when an object is immersed in a fluid stream there is phenomena of friction and turbulence when the fluid is air the study of these phenomena is aerodynamics; when the fluid is water the study of these phenomena is hydrodynamics; the study of hydrodynamic resistance (rh) does not currently have a comprehensive theory that would apply an equation corresponding to .

The aerodynamic forces acting on a baseball are those produced by the contact between the ball and the air and are defined by the initial conditions of the pitch it is well known that such forces determine the changes from the typical parabolic ballistic trajectory either in the direction of the movement of the ball (drag force) or producing a lift or lateral deflection (magnus and seam .

Lift-to-drag ratio the lift-to-drag ratio is a ratio of the lift force to the drag force and it varies across the blade the higher the lift-to-drag ratio the more efficient the turbine blade is at converting wind energy into torque which produces more electricity from the generator turbine blades have the highest lift-to-drag ratio near .
