Energy of Physics, Part I: Classical Mechanics and Thermodynamics

The Energy of Physics, Part I: Classical Mechanics and Thermodynamics provides students the opportunity to learn physics the way in which physicists understand the discipline. In contrast to standard textbooks, which introduce forces first, this text begins with classical mechanics using the concept of energy conservation. By inverting the standard order of presentation, the book enables students to understand and use calculus effectively, particularly toward applications in physics.

Energy conservation is a constant theme throughout the text. Newton’s laws are presented in terms of work and changes in kinetic energy, and forces are introduced as the derivative of potential energy, which is necessary for defining equilibrium conditions. A generalization of forces and Newton’s laws then motivates the concepts of linear and angular momentum. The mode of presentation also allows thermodynamics to be incorporated throughout the text.

The second edition includes a new chapter on fluids and new and additional practice problems for all chapters.

The Energy of Physics, Part I gives students a better understanding of classical mechanics and provides a solid foundation for more advanced physics concepts and courses. The text is ideal for calculus-based physics courses for science and engineering majors.
