中考题中浮力的综合题往往占有较大的比值,总结学生做题实践,归纳如下: 1.明确被研究的对象处于什么样的状态中,如物体在液体中是漂浮、悬浮、还是沉底、上浮还是下沉。比如正确理解关键词,如:“浸入”、“露出”、“浮在”……等。通过分析判断物体处于什么状态,必要时画出状态图进行分析。 The comprehensive questions in the buoyancy test in the examination questions often occupies a large ratio. Summarizing the student’s practice of the questions is summarized as follows: 1. Definite what kind of state the object being studied is in, such as whether the object is floating, suspended, or sinking in the liquid. , floating or sinking. For example, correctly understand the keywords, such as: “immersed in”, “exposed”, “floating in” ... and so on. Through analysis to determine the state of the object, if necessary, draw a state diagram for analysis.
