Quiz 5: Unit 3. Part 3. Question 10. Watch the Unit 3 Part 3 lecture video and answer the following question: According to Kepler's second law. What happens when a planet approaches the Sun in its orbit? A) It speeds up B) It slows down C) Planets maintain a constant speed as they orbit
A) It speeds up
Quiz 5: Unit 3. Part 1. Question 4. Watch the Unit 3 Part 1 lecture video and answer the following question: Simply from the conservation of angular momentum, how fast will a planet with more mass spin compared to a planet with little mass? A) The more massive planet will spin faster B) The more massive planet will spin slower C) Both planets will spin the same rate because mass does not control spin rate
