Acceleration is absolute in relativity even though absolute velocity does not exist
Is it true that acceleration is absolute in relativity even though absolute velocity does not exist?
That acceleration is absolute while absolute velocity does not exist is a foundational principle of both classical mechanics and relativity, representing standard physics that requires no citation.
Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked
The claim states a fundamental axiom of kinematics and relativity (namely, that velocity depends on the choice of inertial reference frame, whereas acceleration is frame-independent and can be measured locally without reference to an external coordinate system). This is a well-established, definitional fact of physics taught in introductory textbooks, making it common knowledge rather than a contestable research hypothesis.
