Summary

Physics is designed to give readers conceptual insight and create active involvement in the learning process. Throughout the book examples are structured to reinforce the problem-solving procedure outlined in Chapter 1, and guide readers down the path taken to find the solution. Companion photos depicting important physics concepts are chosen to complement each other by showing the same principle at work in different physical contexts, or to juxtapose situations in which contrasting principles are at work. Chapter topics cover such headings as electromagnetism, light and optics, and modern physics. This comprehensive book helps readers draw the situation described in the problem statement, visualize the process taking place, identify and label important quantities, and set up coordinate axes. Shows readers how to analyze the problem, identify the key physical principles at work, and devise a plan for obtaining the solution. Contains a unique 2-column format. For readers interested in Algebra-based Physics.
