# Angular Velocity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Angular velocity, abbreviated as $$\omega$$ (Greek symbol omega) or $$v_a$$, also called angular speed, is the speed that an object moves through an angle, θ.  The calculation below calculates ω but does not calculate the relative velocity of a point as it moves throughout the curve.

 $$\large{ \omega = \frac { \theta } { t } }$$                   $$\large{ \omega = \frac { \Delta A } { t } }$$          Where: $$\large{ \omega }$$   (Greek symbol omega) = angular velocity $$\large{ \Delta A }$$ = change in angle displacement $$\large{ t }$$ = time $$\large{ \theta }$$   (Greek symbol theta) = angle distance
