Homework Help: Question about newton's 3rd law

  1. Jan 7, 2008 #1
    haha im kinda dumb and all and my physics teacher is like chinese and very unclear (grade eight).

    Newton's third law states that "For every action, there is an equal and opposite reaction." I understand most of it but have this question, If the reaction and original force are of the same magnitude in opposite directions, how come they do not cancel each other out?
