In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.

FD = (1/2)*ρ*v^2*CD*A

where

FD is the drag force,
ρ is the density of the fluid,
v is the speed of the object relative to the fluid,
A is the cross sectional area, and
CD is the drag coefficient – a dimensionless number.
