浮力的计算问题既是初中物理学习的一个难点,也是中考的一个重点、热点.其实,只要理解了有关浮力的几个基本公式,掌握了解决浮力问题的基本方法和思路,浮力计算问题自然也就成了小菜一碟了.有关浮力的几个基本公式:(1)对于漂浮或悬浮的物体,若知道物体的重力G或质量m,则F浮=G=mg;(2)根据阿基米德原理,不管物体漂浮、悬浮或下沉,若 The problem of buoyancy calculation is not only a difficult point in physics learning for junior middle school students, but also a key and hot topic in the examination. In fact, as long as you understand several basic formulae about buoyancy and master the basic methods and ideas for solving the buoyancy problem, the problem of buoyancy calculation naturally arises. It has become a piece of cake. Several basic formulae related to buoyancy are: (1) For floating or suspended objects, if the gravity G or mass m of the object is known, then F float = G = mg; (2) according to Akemi Principle, whether objects float, float or sink, if
