This is a companion textbook for an introductory course in physics. The purpose is to thoroughly link the theories students learn in class with actual problem-solving techniques. In other words, it addresses the common complaint that 'I feel like I understand the concepts, but I can't do the homework'. This book covers the fundamentals that comprise the majority of a physics course in as simple and concise terms as possible, with a particular emphasis on how the fundamental concepts and equations allow students to solve problems. In addition to updates across the board, this edition includes new material relating to waves, optics, fields, magnetism, and circuits. Each section focuses on a deeper understanding of the equations you will be using along with problem-solving skills. Remember that equations themselves are merely tools and you will be in much better shape if you know what tool you are looking for before you start looking. The book will equip you with the problem-solving techniques and conceptual explanations that can be applied to almost anything in your introductory physics course.
