Air Resistance

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Air resistance is a force that opposes an object as it moves through the air.

Air Resistance formula

(Eq. 1)  \(\large{ F_a = kv^2 }\)

(Eq. 2)  \(\large{ F_a = \frac{\rho C_d A}{2}  v^2 }\)

Where:

\(\large{ F_a }\) = force of air resistance or drag

\(\large{ A }\) = area cross section of the object

\(\large{ \rho }\)  (Greek symbol rho) = atmosphere density object moves through

\(\large{ C_d }\) = drag coefficient

\(\large{ k }\) = a constant that collects the effects of area, density, and drag

\(\large{ v }\) = velocity of the moving object
