Orders of magnitude (angular velocity)
Encyclopedia
This page is a progressive and labeled list of the SI angular velocity
orders of magnitude, with certain examples appended to some list objects.
Angular velocity
In physics, the angular velocity is a vector quantity which specifies the angular speed of an object and the axis about which the object is rotating. The SI unit of angular velocity is radians per second, although it may be measured in other units such as degrees per second, revolutions per...
