The CG will travel in some sort of circles in a dynamic situation around the static CG,can not do anything about it unless we put it on rails.That's probably why race cars have a "stiff" suspension to try and keep the CG and IC in a very general relationship to one another
while moving , and then roll centers come into play as well?...it is not as simple at first glance due to the dynamic nature of forces that
come into play?
But for the general idea of where the CG is, the first picture posted is probably fairly close to the mark.
it is bloody complicated stuff...
only quoting this because it is true... ...of course this applies to all of us trying to get our head around things..
