The Physics Classroom's Momentum and Collisions textbook is the fourth book in its Tutorial Series. The book uses a down-to-earth style and an easy-to-understand language to discuss the physics of collisions in a logical manner. Difficult concepts are presented with the help of informative graphics and a common-sense approach. Interactive quizzes are sprinkled throughout the text to help the learner check for understanding. While committed to a concepts-first approach to learning, The Physics Classroom does not shy away from the teaching of mathematical ideas and the solving of word problems. Learners will appreciate the systematic approach to solving problems that is modeled in the Example Problems. And they will have ample opportunity to perfect their own problem-solving skills by doing the numerous Practice Problems. Each Practice Problem is accompanied by an answer and a complete solution.
