Inertial frames

  1. Feb 28, 2007 #1
    so here r ma doubts
    => it is sometimes heard tat inertial frame of referance is only an ideal concept and no such inertial frame exists.comment.

    =>the accelaration of a particle is zero as measured from an inertial frame of referance . can we conclude tat no force acts on it?

    => a particle stays at rest as seen in a frame. we can conclude tat
    1) the frame is inertal
    2) resultant force on the particle is zero
    3)the frame may be inertial but the resultant force on the particle is zero
    4)the frame may be noninertial but there is a nonzero resultant force.
    (two of the above options are correct. which r those n why?)

    thnx in advance

    There are no 'doubts' in your question. What do you think the answers are?
