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.
