If an object is passing through a fluid or medium then faces retarding or opposing force this force is called Drag Force
Water exerts a force against a fish
Force on moving object by air friction: velocity2 * objects drag coefficient > Force on stationary object by wind: wind speed2 * objects drag coefficient
It is the '''''resistance''''' to flow in a liquid.

Simply put, the coefficient of drag (Cd) is a way to quantify the various factors that affect, and result in, drag on an aerodynamic object. See the link below for an excellent discussion of drag coefficient on the NASA website. An airplane has 4 forces acting upon it and one of them is Drag, a force in the opposite direction of flight. Aeronautical engineers study the forces on a wing but found it easier to use non-dimensional measuresments. Drag is measure in Force (lbs). But Drag Coefficient is a value of force/force. This allows the engineer to produce charts for the numerous airfoil wing designs and have a Drag Coeffecient Chart that can be used for various sizes of wing applications.

"Drag" is the name given to the force of air resistance, or friction in general.
Drag is something that is force exerted. It is a force that is exerted in the opposite direction of movement.
A drag force is a dissipative force. This can be in the form of air resistance or fluid resistance. Drag force is a force that acts opposite to the relative motion of an object moving in a surrounding fluid.
drag.
The force that opposed motion through a fluid is drag.
drag is minimized by aerofoil shape. drag is a force acts on aircraft to minimize speed
