Features: This book is divided into 3 chapters. The first chapter is titled "Conservation Laws in High School Physics," which introduces the human 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 "Applications of Conservation Laws in High School Physics Problem Solving," which first introduces the content, conditions for validity, common scenarios, problem-solving steps, and precautions of various conservation laws. It then uses example problems and critiques to help students deepen their understanding of conservation laws and learn how to use them to solve problems. 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 "Conservation Law Problems in College Entrance Examination Physics." The example problems and exercises in this chapter are selected from the national or provincial/city 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 also provides students with practical opportunities to practice solving problems using conservation methods.
