Walker’s goal is to help you make the connection between a conceptual understanding of physics and the various skills necessary to solve quantitative problems. The pedagogy and approach are based on over 20 years of teaching and reflect the results of physics education research. Already one of the best-selling textbooks in algebra-based physics, The Fourth Edition strengthens both the conceptual foundations and the tools for problem solving to make the book even better suited to today's students.

Physics, Fourth Edition Technology Update, is accompanied by a significantly more robust MasteringPhysics^® —the most advanced, educationally effective, and widely used online physics tutorial and homework system in the world. Additionally, QR codes appear throughout the textbook, enabling you to use your smartphone or tablet to instantly watch interactive videos about relevant demonstrations or problem-solving strategies.
