| توضیحات: | No other book on the market today can match the 30-year success of Halliday, Resnick and Walker's Fundamentals of Physics! In a breezy, easy-to-understand style the book offers a solid understanding of fundamental physics concepts, and helps readers apply this conceptual understanding to quantitative problem solving. This book offers a unique combination of authoritative content and stimulating applications.
* Problem-solving tactics are provided to help the reader solve problems and avoid common errors.
* This new edition features several thousand end of chapter problems that were rewritten to streamline both the presentations and answers.
* Chapter Puzzlers open each chapter with an intriguing application or question that is explained or answered in the chapter.
Like all other sciences, physics is based on experimental observations and ...
When a discrepancy between theory and experiment arises, new theories must be formulated to remove the discrepancy. Many times a theory is satisfactory only under limited conditions; a more general theory might be satisfactory without such limitations. For example, the laws of motion discovered by Isaac Newton (1642 – 1727) in the 17th century accurately describe the motion of bodies at nor-mal speeds but do not apply to objects moving at speeds comparable with the speed of light. In contrast, the special theory of relativity developed by Albert Ein-stein (1879 – 1955) in the early 1900s gives the same results as Newton’s laws at low speeds but also correctly describes motion at speeds approaching the speed of light. Hence, Einstein’s is a more general theory of motion.
Classical physics, which means all of the physics developed before 1900, in-cludes the theories, concepts, laws, and experiments in classical mechanics, ther-modynamics, and electromagnetism.
