从近年的高考题中可以看出,对机械能守恒的考查,题型有选择题、实验题、计算题,难度中等偏上.重力做的功和重力势能、弹力做的功和弹性势能等用功能关系研究物理问题是历年高考的必考内容.现在就机械能守恒定律的判定方法和应用谈点体会.一、机械能守恒定律的判定方法
From the college entrance examination in recent years can be seen in the exam, the conservation of mechanical energy test, the questions are multiple-choice questions, experimental questions, calculation problems, the difficulty of moderate upper gravity and gravitation force, elastic force and elastic potential The study of the relationship between the physical function of the physical examination of the college entrance examination in the compulsory content.Now the conservation of mechanical energy and application of the method to determine the point of experience.Mechanical conservation law of the determination method
