I think your “quest” to find the terms as they relate to motion is a pretty good
example of just how unusual these terms are. Once you go past displacement,
they are hardly common vocabulary. My guess is that nobody has ever come
up with terms in the time domain that have made it into the common vocabulary
describing this stuff.
