Scenario: You are watching your friend riding on his bicycle. Focus your attention to the spinning wheel as it rotates relative to its axis of rotation.  1. Relative to the ground, is the center of the wheel moving? Why or why not? 2. Relative to the wheels' axis or point of rotation, is the center of the wheel moving. Why or why not? 3. Which question can be explained with translational motion? 4. Which question can be explained with rotational motion? 5. At the point where the wheel touches the ground while spinning, the translational velocity is zero, meaning the wheel is not in motion. Is that true? Why or Why not?
