Deceleration

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Deceleration, 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 $$sec$$ $$s$$
