Designed to help students grasp the main ideas in the different topics encountered in A-level physics courses, this text summarizes concepts, highlights uses and limitations, and shows how certain aspects of physics interrelate with other areas. Chapters are broken down into sections, each containing a brief topic summary, the relevant problem, a detailed analysis and the solution, and a selection of questions and answers (some taken from the University of Cambridge Local Examinations Syndicate A Level and Special Paper examinations).
