The surface of the water appears here in beautiful shades of blue, yellow, green, and pink. A drop breaks the surface and starts concentric circular ripples that travel on the surface of the water outward from that point. What do we know about the nature of water and how it absorbs, transmits, and reflects light? How does the reflection of light at particular wavelengths affect the colors our brains interpret? How do waves travel? What affects their speed and frequency? What do water waves have in common with light? How can your knowledge of these basic physics principles be applied to technology, such as the fiber optics used in telecommunications and in arthroscopic knee surgery? The answers to these questions and many more can all be learned through your study of Physics.

"College Physics is intended for a two-semester college course in introductory physics using algebra and trigonometry. The main goals for 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"--

The second edition of this textbook presents a traditional approach to physics, starting with kinematics before moving on to forces. This structure contrasts with the integrated method used in the "College Physics" 3rd edition, which blends the concepts of forces and kinematics throughout. It is designed to provide a clear and straightforward pathway for students to understand fundamental physics principles.

"College Physics, (fourth edition) presents a unique 'forces first' approach to physics that builds a conceptual framework as motivation for the physical principles."--Publisher.
