The second review segment of the Self-Paced Physics Course is presented in this volume and arranged to match study segments 19 through 40. The segment is divided into five subsegments, each of which is composed of a set of problems and solutions. A study guide is provided for each subsegment. The problem set is designed in a back-referencing system, and the scrambling method is used in solution presentation. Directions for reaching solutions are revealed through the use of latent image study guides. The purpose of the review segment is to help students in isolating and organizing essential physics concepts which are common to problem situations.
