I am trying to understand what the coriolis acceleration tells me? I think it's suppose to tell me the path/direction of the alpha term in the equation, if so how do I use interpretations to determine what happens without using calculations?
The Coriolis component of acceleration results from a radial component of velocity within a rotating frame of reference. For example, the ball in the merry-go-round example. Or, air flow due to a low pressure in the center of a hurricane.
This component of acceleration is not directly tied to the alpha (angular acceleration) term.
I would be concerned more about how to find this term than what it means. It is one of the more difficult terms to explain in kinematics.
On that note, if I place my observer on the axis with the "most" motion, meaning a frame of reference that is rotating while simultaneously rotating about another axis, will that make my Va/o rel and Aa/o rel always 0? Then for the rest of the calcuations you just need to consisder both rotations when defining the angular velocity and acceleration of the observer.
