# Average Acceleration

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

## FORMULA

$$\bar {a} = \frac {\Delta v} {\Delta t}$$

Where:

$$\bar {a}$$ = average acceleration

$$\Delta v$$ = velocity differential $$(v_f - v_i)$$

$$\Delta t$$ = time differential $$(t_f - t_i)$$

$$v_f$$ = final velocity

$$v_i$$ = initial velocity

$$t_f$$ = final time

$$t_i$$ = initial time
