c,p. is rather static and a.c. will move depending on aoa, dyanmic pressure (q), and other variables.
Hope this helps as a starter, someone else I'm sure can expand and/or clarify further.
Ok... That clears it up a bit...
but...
I'm a bit confused... according to my books the CP moves with AoA as well as TAS. As an example when accelerating through the transonic region, the CP shifts from about 25% chord to 45% chord...
And the CLmax vs AoA diagram, doesnt it show the CP movment compared to AoA?
