Common Misconceptions About Angular Momentum

Angular momentum is taught in every classical mechanics course. It is a difficult topic with misconceptions commonly forming significant barriers to student success. My intention in writing this paper is to combat some of the most common misconceptions and to help prepare freshman and sophomore students for success in their upper-level classical mechanics courses. The paper begins with a discussion of several fundamental equations relating to angular momentum. A number of special cases are then examined and the paper concludes after presenting a set of three examples.
