Deceleration

Deceleration is the rate of change of velocity, this is the opposite of acceleration.     

Deceleration FORMULA

(Eq. 1)  \(\large{ d = \frac {\Delta v} {t}  }\)

(Eq. 2)  \(\large{ d = \frac {v_f - v_i} {t}  }\)

Where:

\(\large{ d }\) = deceleration

\(\large{ \Delta v }\) = velocity differential

\(\large{ v_f }\) = final velocity

\(\large{ v_i }\) = initial velocity

\(\large{ t }\) = time in which the change occures
