- adj. Describing an accelerating frame of reference in which Newton's laws of motion do not apply
Sorry, no etymologies found.
It’s just that they only exist in noninertial reference frames.
“That way, we’ll be able to measure any noninertial resistance to the shuttlepod’s motion, so it’ll double as a measurement of the density of space out there.”
