In high school we were taught if the center of mass wasn’t on, well, mass, then it was called “virtual”.

Not saying you’re wrong - you’re probably right. But as an engineer, I’ve referred to or been asked about “the center of mass” thousands of times and not once have I ever heard “virtual” used. It’s just always the center of mass - wherever that point exists in all of spacetime.
It’s weird. Did something change over the years (like using the Oxford comma or double spacing after a period?). Or is that something that’s always been a thing that I’ve never run across? Strange ;)

After doing a search online the only reference to a virtual center of mass is a StackExchange post that says it’s from a high school textbook. Must be the same one I had. Seems to be not so common of a term!

I think the correct term would be “mathematical”
