The fifth edition of this algebra-based physics book is designed to help students develop a conceptual understanding of physics principles and to improve their reasoning ability. The authors have developed a problem-solving technique which leads students to an understanding of how physics concepts fit together to provide a coherent description of the physical world. Technology has been integrated throughout, expanding the capabilities of the text, and providing a means for students to discover physics interactively. In addition, the book has been restructured to provide even greater flexibility; new material has been added, and other sections have been moved to the end of main chapters or placed in a separate section near the end, allowing professors a choice in what material to cover.
