In short, any angular quantity is the same as its linear quantity, except it describes the angle between the axis of rotation and the position of object, rather than the distance-based quantities. This is actually a pseudovector and is the result of taking the cross-product (this is out of scope of this book) of the radius of rotation and the angular quantity.
