Can you answer these?

  1. Mar 26, 2009 #1
    When asking about twin paradox, people explained by telling me that the condition isn't symmetric as the accleration isn't relative.
    If accleration isn't relative then can you answer this:
    suppose I place you and your freind in space, far from everything else and also far from each other. Then I will apply gravitational pull on one of you only thus acclerating one of you. Each of you will see other acclerating away. Now to find who is the one I am applying force to acclerate, what experiment would you carry out to find if you are in "real accleration" or not?
    (if you throw a stone, it will still appear to go away in uniform velocity whether you are acclerating or not, as my gravitaional force acts not only on you but everything you throw.)
    --------------------------------------------------------------------
    Also answer my these elementary question about the two clock A and B.
    If I move away clock A and bring it back to B, which will be slower?

    If Clock A moves away from clock B (as seen by clock B) with uniform velocity then will the time on clock A continue to change with that of B or maintain a constant diffrence (from the synchronized time)?

    Suppose Clock A revolve round clock B (then for B, A is acclerating as velocity is constantly changing), what effects will be there on the times, they record.
