Answer
An object in motion along a line has linear momentum.
A rotating object has angular momentum.
Work Step by Step
This is discussed on page 150.
(A more advanced treatment says that an object moving in such a way that its line of motion doesn't pass through a rotation axis has angular momentum. For example, if you run tangent to the rim of a small low-friction turntable and jump on, you can set it spinning with your angular momentum.)
