A marble on a plate can be made to go in a circle. If you give the marble a push while it is in the whole (uncut) plate, it will follow a circular path. 1. After your push, what is the force causing this circular motion? (Hint: the surface of the marble is pushing on the surface of the plate) 2. In what direction is this force? (Hint: think of the definition of this force) A second plate has a section cut out of it. If you give the marble a push near the top so that it travels along the plate counter-clockwise, predict what path you think the marble takes when it exits the plate? 3. Predicted Path 4. Explain why you chose this path:
