浮力章节是初中物理中重要的一节,也是学生普遍觉得较难掌握的一节.虽然浮力的公式并不复杂,但由于物体在液体中分漂浮、悬浮以及下沉三种情况,对其进行正确的受力分析就有了一定的难度.如果浮体本身密度不均匀,那么问题就显得更复杂了.有关浮力的题目活而广,其中以冰块作为浮体的一系列题目是一 The buoyancy chapter is an important section in junior high school physics, and it is also a section that students generally find difficult to master. Although the formula of buoyancy is not complicated, because objects float, float and sink in liquid The correct force analysis has a certain degree of difficulty. If the density of the floating body itself is not uniform, then the problem becomes more complicated. The topics related to buoyancy are wide and wide, and a series of topics with ice cubes as floating bodies is a
