Guide Questions: 1. What happened when you lift the tape up? Did the marble continue to travel in the same circular path for a while and then slow down, or not? 3. What do you think is the reason for your answer on number 1? Hint: For an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the centripetal force requirement. The direction of the net force is in the same direction as the acceleration.

Question
Activity No. 2: The Wonder of Circular Motion 1. Prepare the materials: smooth floor, marble, and roll of masking tape. (You can use alternative objects if they are not available at home as long as they have similarities in form.) 2. Clear out a wide patch of floor. 3. Place the marble inside the roll of tape. 4. Grip the outside edge of the roll of tape with the fingers of one hand. Spin the tape in a circular motion on the floor, not lifting it off the ground. The marble should start going around in a circle. 5. Now, lift the roll of tape and see how the marble travels. 6. Repeat several times.
