# Acceleration

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Acceleration is the rate of change of velocity. Whenever a mass experiences a force, an acceleration is acting.  Acceleration is a vector quantity having magnitude and direction, some of these include displacement, drag, force, lift, momentum, thrust, torque, velocity and weight.

### Acceleration FORMULA

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

$$\large{ a = \frac { v_f - v_i } { t } }$$

Where:

$$\large{ a }$$ = acceleration

$$\large{ t }$$ = time

$$\large{ v }$$ = velocity

$$\large{ \Delta v }$$ = velocity differential

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

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

Solve for:

$$\large{ v = v_i + at }$$

$$\large{ v_i = v - at }$$
