Homework Help: Center of gravity and Newton's 3 Law of Motion.

  1. Jul 25, 2011 #1
    I have a project to do and I have to make a demonstration about a physics phenomenon. I'n planning on doing a demonstration that explains one or all of Newton's Laws of Motion. I've chosen to do it on the center of gravity, but I want to know if it's
    related to Newton's 3 Laws of Motion or is it not?

    third law is "every action has an equal and opposite reaction"

    so some demonstrations may work and some may not

    whats in your mind?

    Well in my demonstration, I'm planning on taking an empty can and filling it with 1/3 of water to make it rotate in a circular motion on its edge. After I'm going to fill it with smashed ice instead of water and do the same thing.

    Ok, I am a bit confused ... how is 3rd law demonstrated in it?
