Terminal Velocity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

velocity terminalTerminal velocity ( \(v_t\) ) is when an object is falling under the influence of gravity but with no other influences.

Terminal Velocity formula

\(\large{ v_t =   \sqrt {  \frac {2mg} {C_d \rho A}  }   }\)         

\(\large{ v_t =   \sqrt {  \frac {2W} {C_d \rho A}  }   }\)         

Where:

\(\large{ v_t }\) = terminal velocity (maximum falling speed)

\(\large{ A }\) = area of the object

\(\large{ \rho }\)   (Greek symbol rho) = density of the fluid

\(\large{ C_d }\) = drag coefficient

\(\large{ g }\) = gravitational acceleration

\(\large{ m }\) = mass

\(\large{ W }\) = weight of the object
