Newton's Third Law of Motion

  1. Nov 1, 2008 #1
    1. The problem statement, all variables and given/known data
    How does Newton's Third Law of Motion apply to a tetherball?

    2. Relevant equations

    3. The attempt at a solution
    Forces always occur in pairs (action/reaction force).
    I know that when you're pushing on a wall, the wall pushes back on you, which is why you don't move at all. But what is the reaction force from the tetherball?

    The tetherball situation is similar to you pushing on the wall.

    The pole is pulling on the ball through the rope connecting them. So, what is the ball doing to the pole through the rope?

    Okay. I think I got it. Thank you!
