Lesson 3 - Lecture 1 - Explanation of Planetary Motion - OpenStax Astronomy 2e

In this lecture, we will look at how planetary motion could be explained based on the observations of Tycho and the calculations of Kepler. A change came by Kepler finding that planetary motion could be more easily by abandoning the concepts of circular motion and uniform speeds.

Note: Lesson 0 materials are specific for the classes that I teach. Lesson 1 will start with Chapter 1 of the textbook.
