UNIT 7 Torque and Rotation 7.C Rotational Energy NAME Scenario A solid sphere is initially at rest at the top of a tall, rough hill. It rolls down the hw and up the next hill. Using Representations PART A: Angela, Blake, and Carlos each create an energy bar chart for the sphere- Earth system for the time between when it is released from rest at point A and when it reaches point B. For each graph, explain why it is either corrector incorrect Angela Blake Carlos B AB AB К к о 1K, KUA 1кко 1к, к, . К. к. о 1ка к од 7. Rotational Energy PART How would each of the bar charts drawn in Part A be differentif Earth were not part of the system? PARTO The sphere continues to roll along the track without slipping and at point. It leaves the track. At the sphere's highest point, will it be above, below, or at the same height as pointA? Explain your meaning Above Below Below Same Height PARTO The sphere is then taken to an identically shaped track with negligible friction and released from point A. Is the sphere's maximum height after leaving the track greater than less than or the same as the height it reached on the rough track? Greater than Less than Same as Explain your reasoning
