In the figure below, Planet X is moving in a perfectly circular orbit around its companion star.The time between each position shown is exactly one month:
1. Write down Kepler’s second Law of planetary motion.2. Does the planet obey Kepler’s second law? How do you know?3. If you carefully watched this planet during the entire orbit, would its speed be increasing, decreasing, orstaying the same? How do you know?
1. Why were the main reasons why the idea that the Earth was at the center of the universe lasted so long?
2. Discuss in 2 paragraphs the observations made by Galileo that disproved Geocentrism. Which one do you think was the most important?
3. Write down a hypothesis and observational experiment to test one of Newton’s laws of motion. EXPLAIN YOUR REASONING!
4. One of the first exoplanets discovered orbits the star 51 Pegasi with a period of just 4.2 days. 51 Pegasi is very similar to the Sun. Use Kepler’s laws to find the distance (in astronomical units) between the planet (unofficially named Bellerophon) and its star. SHOW YOUR WORK!
5. How does halving the distance between two objects affect the gravitational force between them?
6. Suppose the Sun were somehow replaced by a star with five times as much mass. What would happen to the gravitational force between the Earth and the Sun?
