## Average Velocity

Average velocity ($$\bar {v}$$ ) is the average of any given velocities where the acceleration is constant.

### Average Velocity FORMULA

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

Where:

$$\large{ \bar {v} }$$ = average velocity

$$\large{ v_f }$$ = final velocity

$$\large{ v_i }$$ = initial velocity
