浮力是初中物理重要考点之一,也是同学们感觉较难学的知识点.用实验探究浮力的有关知识、应用不同方法求浮力大小和用浮力知识解决实际问题等一直是中考的热点,现结合2007年中考题的分析,与同学们一起探讨中考浮力命题的规律和解题思路. Buoyancy is one of the important physics test sites for junior high school students. It is also a knowledge point that the students feel is difficult to learn. Exploring the relevant knowledge of buoyancy, using different methods to find the buoyancy and using buoyancy knowledge to solve practical problems has always been the focus of the examination. In 2007, the analysis of the Chinese exam questions was discussed with the students to discuss the rules of the buoyancy proposition and the problem-solving ideas.
