Name: Date: Uniform Circular Motion Activity Goal: to analyze the forces needed for circular motion and understand what happens when those forces are removed. Instructions: Answer the following and as materials to complete the activity, two plastic plates and a marble. (value: 40pts) link- https://www.youtube.com/watch?v=biDtoZOTCOM A marble on a plate can be made to go in a circle. If you give the marble a push while it Force List is in the whole (uncut) plate, it will follow a circular path. Centripetal 1. After your push, what is the force causing this circular motion? Friction (hint: the surface of the marble is pushing on the surface of the plate) Gravity 2. In what direction is this force Normal (hint: think of the definition of this force) Tension B 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? D 3. Predicted path. 4. Explain why you chose this path. Test out your guess with the plate and marble. Do the experiment several times to make sure you know what actually happens. 5. What path does the marble take when it leaves the plate? 6. Does this agree with Newton's 1" law of motion? Why/why not? https://betterlesson.com/lesson/635540/playing-a-round-with-circular-motion Antilles Military Academy "Our mission consists in fostering academic and leadership skills and values that will enable students to be prepared for university entrance. " The picture on the right represents a marble going in a circle around a plate and the marble is moving counterclockwise. 7. What happens if you remove the force causing the marble to go in a circle?_ 8. Draw the force vector acting on the marble. 9. Draw the velocity vector at that moment (Note: vectors are always arrows and are represented with a straight line. They show the objects velocity or force at that moment)
