Direction of the Angular Velocity Vector
In physics, the angular velocity is described as the rate of change of angular displacement and is a vector quantity (more precisely, a pseudovector) that exacts the angular speed (rotational speed) of an object and the axis about that the object is rotating. The SI unit of angular velocity is radians per second, while it may be measured within other units such as degrees per second and degrees per hour and etc.
