Homework Help: CM conceptual question

  1. Apr 27, 2007 #1
    1. The problem statement, all variables and given/known data

    Does the CM of a system of particles depend on whether the particles are interacting or non-interacting?Will the positon of CM change in another inertial or non-inertial frame?

    2. Relevant equations

    3. The attempt at a solution

    My attempts:Please check.
    CM is invariant -no matter whether the particles are interacting or non-interacting-whether ther is a relative motion or not within the system as long as we are dealing with the same system of particles.

    CM of a system of particles can be shown to be invariant w.r.t. any origin of an arbitrary reference frame.So,it must be the same even in an inertaial or non-inertial frame of reference.

    Yeah. Thats right. Think so.
