In fluid dynamics, the drag coefficient (commonly denoted as C d , C x or C w ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid env...

The force on an object that resists its motion through a fluid is called drag. When the fluid is a gas like air, it is called aerodynamic drag (or air resistance). When the fluid is a liquid like water it is called hydrodynamic drag (but never "water resistance").

For real body shapes, air at standard conditions, V in mph, and drag in pounds of force, this equation becomes: ... Here are measured drag coefficients for some basic shapes. These numbers come from tests of shapes with known cross sectional areas. You blow air over them and measure the force on the shape.

Note that unlike traditional formulae for aerodynamic drag, here the force is proportional to the _square-root_ of area, not area directly, so a "drag coefficient" is not really appropriate. This makes some kind of sense to me.
