Deceleration

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

deceleration 1Deceleration, abbreviated as d, is the rate of change of velocity, this is the opposite of acceleration.

    

Deceleration formulas

\(\large{ d = \frac {\Delta v} {t}  }\)   
 \(\large{ d = \frac {v_f \;-\; v_i} {t}  }\)  

Where:

 Units English Metric
\(\large{ d }\) = deceleration \(\large{ \frac{ft}{sec^2} }\) \(\large{ \frac{m}{s^2} }\)
\(\large{ \Delta v }\) = velocity differential \(\large{ \frac{ft}{sec} }\) \(\large{ \frac{m}{s} }\)
\(\large{ v_f }\) = final velocity \(\large{ \frac{ft}{sec} }\) \(\large{ \frac{m}{s} }\)
\(\large{ v_i }\) = initial velocity \(\large{ \frac{ft}{sec} }\) \(\large{ \frac{m}{s} }\)
\(\large{ t }\) = time in which the change occures \(sec\) \(s\)
