For courses in liberal arts physics. Actively engage students in learning and loving physics. Paul Hewitts best-selling Conceptual Physics defined the liberal arts physics course over 30 years ago and continues as the benchmark. Hewitts text is guided by the principle of "concepts before calculations" and is famous for engaging students with real-world analogies and imagery to build a strong conceptual understanding of physical principles, ranging from classical mechanics to modern physics. The 13th Edition continues to make physics delightful for students with informative and fun Hewitt-Drew-It screencasts, updated content and applications, and new engaging activities. Pearson Mastering® Physics is not included. Students, if Pearson Mastering Physics is a recommended/mandatory component of the course, please ask your instructor for the correct ISBN. Pearson Mastering Physics should only be purchased when required by an instructor. Instructors, contact your Pearson representative for more information.
