Equivalence of all inertial frames
What Equivalence of all inertial frames means in Physics A-Level, as defined for AQA.
Definition of Equivalence of all inertial frames
Check what you remember
Read the wording for your board, then hide it and explain Equivalence of all inertial frames in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Physical laws have the same form in all inertial frames, so no inertial observer can perform an experiment that reveals absolute rest or absolute motion.
