Average Velocity

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Average velocity, abbreviated as \(\bar {v}\) or \(v_a\), also called constant acceleration, is the average of any given velocities where the acceleration is constant.  The calculation for average velocity with zero accleration is shown below.

Average velocity formulas

\(\large{ \bar {v} = \frac{ 1  }{ 2 }  \left( v_i + v_f   \right) }\)   
\(\large{ \bar {v} = \frac{ v_i \;+\; v_f  }{ 2 }  }\)   
\(\large{ \bar {v} = \frac{ d  }{ t }    }\)   

Where:

\(\large{ \bar {v}  }\) = average velocity

\(\large{ d }\) = displacement

\(\large{ v_f  }\) = final velocity

\(\large{ v_i  }\) = initial velocity

\(\large{ t }\) = time
