中考力学所占比重较大,对力学的掌握直接影响物理考试成绩。而浮力又是力学部分学习的绊脚石,浮力其解题方法的多样,解题公式的多变,往往让同学们不知道如何作答。然而浮力知识中的液面升降问题,又是学习浮力过程中的一个难点,通过多年对中考题的分析,结合学生的理解方式,特对此类问题做了总结分析。
The proportion of senior high school entrance examination mechanics, mechanical mastery of a direct impact on physical examination scores. Buoyancy is also a stumbling block in the study of mechanics. Buoyancy has a variety of methods for solving problems, and the formula for solving problems has changed so often that students do not know how to answer them. However, the problem of liquid surface lift in buoyancy knowledge is another difficulty in learning buoyancy. Based on the analysis of many years of examination questions and students’ comprehension methods, this paper summarizes and analyzes such problems.
