College Physics is intended for a two-semester college course in introductory physics using algebra and trigonometry. Our main goals in writing this book are to present the basic concepts of physics that students need to know for later courses and future careers, to emphasize that physics is a tool for understanding the real world, and to teach transferable problem-solving skills that students can use throughout their lives. We have kept these goals in mind while developing the main themes of the book. NEW TO THIS EDITION Although the fundamental philosophy of the book has not changed, detailed feedback from over 170 reviewers (many of whom used the first edition in the classroom) and 10 class tests have enabled us to fine-tune our approach to make the text even more user-friendly, conceptually based, and relevant for students. The second edition also has some added features to further facilitate student learning.
