The principle that objects in an accelerating reference frame experience fictitious inertial forces proportional to acceleration is a fundamental tenet of classical mechanics, making it common knowledge that requires no citation.
The claim states a foundational principle of classical physics (inertial forces like the centrifugal or Euler force in non-inertial frames being proportional to acceleration). None of the retrieved papers specifically target or investigate this textbook physical law as an empirical hypothesis under test; rather, the retrieved literature covers specialized topics such as heart valves, hydrogen embrittlement, computational nanoreactors, and vehicle dynamics. Consequently, the claim is classified as common knowledge.
