This text is a guide for high school teachers, college faculty, and graduate teaching assistants involved in introductory physics teaching. Teaching Physics is a combination of the previous Guide to Introductory Physics Teaching, and Homework and Test Questions for Introductory Physics Teaching. Both works have been edited to incorporate suggestions and feedback received after the first publication. Added to this combination is a monograph intended to illustrate how certain misleading aspects, widely prevalent in existing text presentations, can be rectified in introductory teaching of the energy concepts. This is intended as a guide and resource for active teachers at college and high school level.
