密度、浮力是初中物理探究的重要内容。两者虽然是性质不同的物理量,但知识间有着必然的联系,其应用也相当广泛。浏览全国各地物理中考竞赛试题,不难发现密度与浮力相关联、交融、综合的试题屡见不鲜、异彩纷呈。下面就立足于两者知识的关联点,对考题进行分析。 Density and buoyancy are important topics for junior high school physics. Although the two are physically different physical quantities, there is an inevitable link between knowledge, and its application is also quite extensive. When you look at the physics exam contests across the country, it’s not hard to find that the questions related to density and buoyancy, blending, and comprehensive tests are common and colorful. The following is based on the connection between the two points of knowledge to analyze the questions.
