浮力问题涉及到受力分析、物体体积与排开液体体积以及物体密度与液体密度的分析与应用。对于动态情况下的浮力问题,我们可以选取不同的阶段进行分析,因此同一个问题可能会有多种解法。下面我们就用不同视角下的多种方法解答一道中考浮力考题。 The problem of buoyancy involves the analysis and application of force analysis, object volume and liquid volume, as well as object density and liquid density. For the dynamic buoyancy problem, we can choose different stages for analysis, so the same problem may have a variety of solutions. Here we use a variety of ways under different perspectives to answer a builder test builder.
