# Acceleration

Acceleration is the rate of change of velocity. Whenever a mass experiences a force, an acceleration is acting.

## FORMULA

\(a = \frac {\Delta v} {t} \)

\(a = \frac {v_f - v_i} {t} \)

Where:

\(a\) = acceleration

\(\Delta v\) = velocity differential

\(v_f\) = final velocity

\(v_i\) = initial velocity

\(t\) = time in which the change occures

Solve for:

\(v = v_i + at\)

\(t = \frac {v - v_i} { a} \)

\(v_i = v - at\)
