The coefficient associated with this quantity is equal to 24 over the Reynolds number at small values of the Reynolds number; for Reynolds numbers above 1, Goldstein's approximation is often used to approximate this quantity's value. For a sphere, this quantity is equal to six pi times the viscosity times the radius times the velocity, by (*) Stokes's Law. In aerodynamics, this quantity opposes thrust. When this quantity equals the gravitational force, an object has reached terminal velocity. For 10 points, name this fo

When this quantity equals the gravitational force, an object has reached terminal velocity. For 10 points, name this force that retards an object's motion through a fluid and is overcome by vehicles through thrust or lift.
