Building on the research-proven instructional techniques introduced in Knight's ''Physics for Scientists and Engineers, '' the most widely adopted new physics text in more than 30 years, ''College Physics: A Strategic Approach'' set a new standard for algebra-based introductory physics--gaining widespread critical acclaim from professors and students alike. For the Second Edition, Randy Knight, Brian Jones, and Stuart Field continue to apply the best results from educational research and refine and tailor them for this course and the particular needs of its students. New pedagogical features (Chapter Previews, Integrated Examples, and Part Summary problems) and fine-tuned and streamlined content take the hallmarks of the First Edition--exceptionally effective conceptual explanation and problem-solving instruction-to a new level. More than any other book, College Physics leads you to proficient and long-lasting problem-solving skills, a deeper and better-connected understanding of the concepts, and a broader picture of the relevance of physics to your chosen career and the world around you. College Physics Technology Update, Second Edition, is accompanied by a significantly more robust MasteringPhysics(R)--the most advanced, educationally effective, and widely used online physics tutorial and homework system in the world.
