Features: This book is divided into 3 chapters. The first chapter is titled "Conservation Laws in High School Physics," which introduces the historical development of humanity's understanding of conservation concepts from the perspective of the history of physics. It helps students realize that scientific inquiry is a challenging and creative activity, not a smooth journey. The path to scientific heights is filled with obstacles and risks. A new scientific discovery or the birth of a new scientific theory often requires the relentless efforts of several generations. The second chapter is titled "Applications of Conservation Laws in Solving High School Physics Problems." It first introduces the content, conditions for validity, common scenarios, problem-solving steps, and precautions of various conservation laws. Then, through example explanations and evaluations, it helps students deepen their understanding of conservation laws and learn the steps and methods for solving problems using conservation laws. Additionally, each section is accompanied by corresponding exercises to guide students in applying the methods they have learned to solve new problems. The third chapter is titled "Conservation Law Problems in College Entrance Examination Physics." The examples and exercises in this chapter are selected from national or regional college entrance examination physics questions from the past 10 years. On one hand, it helps students better understand the college entrance examination and get closer to it. On the other hand, it provides students with practical opportunities to apply conservation methods to solve problems.
