New to this editionNew â€ŔConnections” feature identifies areas in each chapter where important concepts are revisited. A marginal â€ŔConnections” heading and summary adjacent to the coverage in the main text help students easily recognize that a previously introduced concept is being applied to the current discussion. New Checkpoint questions have been added to applicable sections of the text. The answers to the Checkpoints are found at the end of the chapter. Non-essential coverage and derivations have been moved from the text to the textâ€â¢s online site. Identifiers in the text direct students to additional information online. Electronic Media Integration has been incorporated throughout the text. Icons indicate topics in the text where accompanying interactives, animations, and tutorials can be found online to aid in student understanding of physics concepts. The topical question from the chapter opening vignette now appears in the margin (along with a reduced version of the chapter opening image). Applications have been clearly identified as such in the text with a complete listing in the front matter. Many helpful subheadings have been added to the text to help students quickly identify new subtopics.
