Question

Can someone please give a good equation for terminal velocity that takes into account drag and air resistance? Thanks in advance.

Answer 1

Mathematically, terminal velocity, without considering the buoyancy effects, is given by

  

Vt = √[ (2mg)/(pACd) ]

where

Vt = terminal velocity,

m = mass of the falling object,

g = gravitational acceleration,

Cd = drag coefficient,

ρ = density of the fluid through which the object is falling, and

A = projected area of the object

Drag coefficient
