Stupid question

  1. Nov 21, 2004 #1
    Why we move foward:

    The applied force from our foot pushs on the earth and therefore, according to Newton's 3rd law, the Earth pushes back on me to make me move foward.

    Yeah, this is like basic material, but just need a verification, is this correct?

    I'll second that, and add that this is really not such a stupid question at all. Newton's 3rd Law is the most misunderstood high-school physics concept.

    I'll second Gokul's comment. I sure as hell can't identify an action-reaction pair when I see one so I don't even bother to answer those questions for people.
