[catalogued under 27. Natural Reality / B. Modern Physics / 1. Relativity / a. Special relativity]

Full Idea

There is no absolute state of rest; only relative motions are unambiguous. Contrast this with acceleration, however, which has the same magnitude in all inertial frames.

Gist of Idea

All motions are relative and ambiguous, but acceleration is the same in all inertial frames
