The symbol for angular velocity is (pronounced “omega”). Mathematically = t Angular Velocity is radians corresponds to a full circle measured in radians per second (rad/s), where 2π (3600). A little recap on radians An angle (in radians) is defined as the arc length divided by the radius, i.e. = arc length/radius. For a full circle the arc length is in this case becomes radians. This allows us to convert from 2πr, so 2π radians to degrees if we need to radians = 3600) (2π
