I think someone mentioned this before, but there is an excellent discussion of this issue in Arons' A Guide to Introductory Physics Teaching, p. 67. The point is that the reaction is not always instantaneous to the action (cf: the push on one of a rod being communicated to the other end). As Arons points out, Newton's Third LAw isn't always true, which is why the Conservation of Momentum is given more emphasis in modern physics. -- ------------------------------------------------------------------------------- Van E.
