how it changes with mass, size , weight , density.
These are easy, COM scales with the dimensions of the object.
"etc., etc.?" Those get a little tougher. Anything in particular? Geometry? Density gradient?

Example, how does the center of mass change when weights of say 50 Newtons are applied to the undersides of a bus , I understand that the mass will affect (how easy it tips) during a turn but how does this come into play when calculating center of mass or center of Gravity whichever is easier ?
