The Energy of Physics, Part I: Classical Mechanics and Thermodynamics

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

Energy conservation is also a constant theme throughout The Energy of Physics. Newton's laws are first 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 Energy of Physics gives students a better understanding of classical mechanics and provides a solid foundation for more advanced physics concepts and courses. The fresh, unique approach of The Energy of Physics makes it an ideal teaching tool for calculus-based physics courses for science and engineering majors.
