Average Angular Acceleration

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Average angular acceleration ( \(\bar {\alpha}\) (Greek symbol alpha) ) of an object is the average rate at which the angle velocity changes with respect to time.

Average Angular Acceleration Formula

\(\large{ \bar {\alpha} = \frac { \Delta \omega } { \Delta t }   }\)         

\(\large{ \bar {\alpha} = \frac {  \omega_f - \omega_i } { t_f - t_i }   }\)         

Where:

\(\large{ \bar {\alpha}}\)  (Greek symbol alpha) = average angular acceleration

\(\large{ \Delta \omega }\)  (Greek symbol omega) = change in angular velocity

\(\large{ \omega_f }\)  (Greek symbol omega) = final angular velocity

\(\large{ t_f }\) = final time

\(\large{ \omega_i }\)  (Greek symbol omega) = initial angular velocity

\(\large{ t_i }\) = initial time

\(\large{ \Delta t }\) = time differential
