Is there conventional terminology to distinguish between scalars that transform between frames and those that don't? For example, energy is a single-component quantity but it isn't the same in every frame, whereas the length of a vector is also a scalar but is the same in every frame. Do we just call these both scalars, and be precise about what we mean, or are there terms for these different kinds of single-component quantities?
