Discussion Overview

The discussion revolves around the definition and understanding of synchronised clocks, particularly in relation to different frames of reference and the effects of acceleration on their synchronisation. The scope includes conceptual clarification and implications within the framework of relativity.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant proposes a definition of synchronised clocks as "2 clocks in a frame of reference that measure time at the same rate and appear to an observer within that same frame of reference to show the same time."
  • Another participant agrees that the definition sounds proper but expresses uncertainty about its correctness.
  • A different participant questions whether two clocks that are synchronised in a stationary frame of reference remain synchronised after the frame is accelerated to a constant velocity.
  • One reply suggests that if both clocks remain in the same frame, they should still be synchronised, but the responder notes a lack of expertise in relativity and recommends waiting for a more knowledgeable input.
  • A later post indicates that the question about synchronisation after acceleration has been asked in another forum, leading to the locking of the thread for further discussion elsewhere.

Areas of Agreement / Disagreement

Participants express differing views on the definition and implications of synchronised clocks, particularly regarding their behaviour under acceleration. The discussion remains unresolved as participants have not reached a consensus.

Contextual Notes

The discussion does not clarify the assumptions underlying the definition of synchronised clocks or the conditions under which they remain synchronised after acceleration. There is also a lack of detailed exploration of relativistic effects on time measurement.

I was wondering what is the definition of synchronised clocks...is it

"2 clocks in a frame of reference that measure time at the same rate and appear to an observer within that same frame of reference to show the same time"

Welcome to PF, Rab.
That sounds like a proper definition to me, but I'm not positive about it.
 
synchronised clocks

is two clocks are synchronised in a stationary frame of reference and then that frame of reference is accelerated to a constant velocity are the clocks still synchronised ?
 
If both of them remain in the same frame, then the answer should be 'yes'. I'm no expert on Relativity, though. It's probably best to wait for a real scientist to weigh in with some answers for you.

You've also asked this question in the Relativity forum, which is the proper place for it. Therefore I'm locking this thread. Anyone who wants to pursue this question should look in the Relativity forum for it.
