Conservative system

  1. Jul 21, 2009 #1
    Hello,

    Could someone tell me what a conservative system in classical mechanics is? Is it

    a) a system in that each particle's total energy is constant

    OR

    b) a system whose total energy is constant, but the individual particles' total energies may change.


    THX, fortaq

    the answer is b)

    Conservative in terms of what?

    If it's in terms of matter, then it's a 'closed' system.

    If its matter and energy it's an 'isolated' system.

    In terms of matter and energy.

    But is a conservative system in fact identical with an isolated one?

    To add to my initial question:
    Is a conservative system not a system in that all forces are conservative? In that case, namely, answer a) should be true.
