Name: 1. How many laws did Kepler use to define planetary motion? 1 point 2. What are the laws? 6 points 3. Explain eccentricity. 4 points 4. Draw two diagrams that illustrate the difference between a high eccentricity and low eccentricity. 4 points Kepler’s Laws Research Activity Directions: Doing research on your own, answer the following questions.

5. Explain the Law of Orbits. 3 points 6. Using words and illustrations, explain the Law of Areas. 5 points 7. Explain the Law of Periods (aka Law of Harmonies). 5 points 8. Using the Law of Periods, prove that Pluto’s orbit is 248 Earth years. 4 points

9. Create your own word problem using the Law of Periods. Show the solution. 4 points 10. Using the idea that the force of gravity is equal to the centripetal force of an object in orbit, show the derivation of the Law of Periods using Newton’s Law of Gravitation. (Hint: set these two equations equal to one another, the velocity of an object in nearly circular orbit is distance (the circumference of the circular orbit) over time (the period of orbit). 4 points 𝐹 ௚௥௔௩௜௧௬ ൌ 𝐺𝑚 ଵ 𝑚 ଶ 𝑟 ଶ 𝐹 ௖௘௡௧௥௜௣௘௧௔௟ ൌ 𝑚𝑣 ଶ 𝑟
