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.
This section will deal with circular motion and its various forms. It will also show how equations used for linear motion can be reused for rotating bodies.

A composite figure is a geometric figure which is formed by—or composed of—two or more basic geometric figures. We will look at a handful of fairly simple examples, but this concept can of course be extended to much more complicated figures.
