Is acceleration absolute and velocity not?

Click For Summary
The discussion centers on the nature of acceleration and velocity, questioning whether acceleration is absolute while velocity is relative. Participants argue that all cinematic quantities, including velocity and acceleration, depend on the reference frame, making them relative rather than absolute. It is noted that while Newtonian physics treats acceleration as absolute, General Relativity posits that all motion is relative, with acceleration observed differently in various frames. The conversation also touches on the implications of relativistic effects and the distinction between inertial and non-inertial frames, emphasizing that acceleration can be measured absolutely under certain conditions. Ultimately, the complexity of defining these quantities in different contexts highlights the ongoing debate in physics regarding their fundamental nature.

Not unless they eventually lead to testable predictions.

you are a new Francis Bacon :-p
