Average Angular Acceleration

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

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


Formulas that use Average Angular Acceleration

\(\large{ \bar {\alpha} = \frac { \Delta \omega } { \Delta t }   }\)   
\(\large{ \bar {\alpha} = \frac {  \omega_f \;-\; \omega_i } { t_f \;-\; t_i }   }\)   


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

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

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

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

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

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

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