Principles of Physics - Tapa dura

The second edition includes a stronger conceptual approach, offering new conceptual examples and problems, and it presents contemporary physics topics early to gain student interest. This book is intended for the science and engineering physics course. Features: * Topics in 20th-century physics, such as relativity and the Bohr atom, are introduced early in the text. * Worked Examples of varying difficulty reinforce material and serve as models for solving end-of-chapter problems. * Exercises with Answers represent extensions of worked examples and encourage students to utilize their problem-solving skills. * Margin Notes help students locate and review important statements, concepts, and equations. * Problem-Solving Strategies and Hints help students identify important procedures and understand the logic behind solving various types of problems. * End-of-Chapter Questions and Problems focus on conceptual understanding of material and challenge students to apply principles just learned. New to this edition: * Thinking Physics conceptual examples have been added to the text to help students gain a better conceptual understanding of material. * Conceptual Problems allow students to apply the concepts learned in Thinking Physics to problem-solving. Answers are provided at the end of the chapter. * The former chapter on Forces and Fields in Nature has been deleted, moving the topics of the fundamental forces in nature and the gravitational field to other chapters. * New chapter (15) on fluid mechanics provides valuable information, especially to those pursuing a career in mechanical engineering or the life sciences. * The material on oscillatory motion and waves is now covered earlier, following mechanics. * The chapters covering interference and diffraction of light waves have been consolidated into one chapter (27), Wave Optics. * Polarization of light is now treated earlier in Chapter 24, Electromagnetic Waves. * Fission and fusion have been moved to Chapter 30, Nuclear Physics.
