- A MORE CAREFUL AND COMPREHENSIVE APPROACH TO PROBLEM-SOLVING FRAMEWORKS. This includes a new general problem-solving framework that applies across units, new tools for solving specific kinds of problems, and more general instruction in problem-solving in the text.
- A NEW APPROACH TO EMPHASIZING IMPORTANT FORMULAS. The new edition puts crucial formulas in boxes that also display important information about its purpose and limitations and what its symbols mean.
- MANY MORE PHOTOGRAPHS help make the text more visually interesting and help link the concepts to physical reality.
- TWO-COLOR LAYOUT WITH COLOR TIED TO PEDAGOGICAL GOALS. Color is used to emphasize the imaginary elements we add to a situation when we construct a mental model.
- UNIT E (Electromagnetic Fields) HAS BEEN REWRITTEN to reduce the level of the mathematics, more strongly emphasize the concept of potential, and more strongly emphasize visual arguments.
- UNIT C (Conservation Laws) HAS BEEN REORGANIZED to increase the time spent on the difficult topics of collisions and angular momentum, to introduce the concept of force sooner, and to present the material in a more efficient manner.
- UNIT N (Laws of Physics) HAS BEEN SIMPLIFIED to reduce the level of the mathematics in various chapters, to use more visually-based lines of reasoning, and to more strongly emphasize computer solutions to realistic problems.
- NEW MATERIAL IN UNIT T (Thermodynamics, gases...) includes a treatment of the Boltzmann Factor and a more realistic exploration of degrees of freedom in gas molecules. This unit also discusses several new computer programs that help students more easily visualize important ideas.
