Homework Help: Reaction force

  1. Jul 6, 2008 #1
    When a leaf begins to fall to a ground from a tree, what is the reaction force ot the force of gravity on the leaf?

    Is it air resistance?

    You are miss-understanding the concept of action-reaction forces; the action-reaction pair act on different bodies. If the earth exerts of force of magnitude mg on the leaf, then the leaf exerts a force of equal magnitude on the earth but in the opposite direction.
