Matter and Interactions, Volume 2: Electric and Magnetic Interactions, 5th Edition Matter & Interactions is a calculus-based introductory physics text that reflects a modernized view of physics. It stresses reasoning from powerful physics principles and integrates contemporary insights such as the atomic nature of matter, quantized energy, and relativistic dynamics throughout the curriculum. Students engage in the full process of creating and refining physical models. Computational modeling is integrated to allow students to apply fundamental principles to more complex, realistic systems, and to explore the possible ranges of behavior of physical models. Joining Ruth Chabay and Bruce Sherwood for this edition as authors are longtime collaborators Aaron Titus (North Carolina State University), and Stephen Spicklemire (University of Indianapolis) who have made great impacts on the new video series, interactive figures, and simulations. The new edition is thoughtfully updated with extensive content revisions, including chapter and section level learning objectives, clarified and simplified initial presentation of key concepts and techniques, and the introduction of angular momentum earlier, before collisions.
