Ok, when talking about rotating bodies, we deal with the following accelerations - please correct me if I am wrong:

A radial acceleration (a.k.a. the centripetal-acceleration): w^2*r or v^2/r.

An angular acceleration given by dw/dt.

A tangential acceleration given by r * a_angular

Where does linear acceleration come in? If we e.g. look at a uniform circular motion, it has a radial acc., no angular and then no tangential but it has a linear acceleration because it changes direction all the time?

I am quite confused about linear acceleration, and I can't seem to find it described anywhere.
