  8. Kepler’s First Law of Planetary Motion • Each planet’s path around the sun is an ellipse, with the Sun at one focus of the ellipse. • http://www.gravitywarpdrive.com/NGFT_Images/Kepler_1st_Law.gif

  9. Kepler’s Second Law (areas, time, and angular momentum) • http://physics.syr.edu/courses/java/mc_html/kepler_frame.html • A planet moves along its elliptical path with a speed that changes in such a way that a line from the planet to the Sun sweeps out equal areas in equal intervals of time. http://schools.wikia.com/wiki/Newton%27s_Law_of_Universal_Gravitation http://hyperphysics.phy-astr.gsu.edu/HBASE/imgmec/kep6.gif

  10. Kepler’s Third Law of Planetary Motion a = Semimajor axis = average distance to Sun P = Orbital period = time for one full orbit around Sun C = Constant whose value depends on the physical units used for a and P The ratio of the cube of the semimajor axis of a planet’s orbit (a) to the square of its orbital period around the Sun (P) is the same for each planet (C) a3 P2 http://images2.wikia.nocookie.net/schools/images/9/9b/Kepler%27s_third_law.gif
