浮力是初二物理中的一个难点 ,是同学们最头痛的问题。因为浮力比较抽象 ,涉及的物理量多 ,解决起来不易理清头绪。利用等式可以较好地解决浮力问题 ,其方法可归纳为四步 :一、对物体进行受力分析出现的情况如下 : ( 1 )物体漂浮 ( 2 )物体悬浮 ( 3 )物体Ａ刚好没入
Buoyancy is a difficult problem in the second day of physics and it is the most headache for students. Because buoyancy is relatively abstract and involves many physical quantities, it is not easy to solve the problem. The equation can be used to solve the buoyancy problem. The method can be summarized as four steps: First, the force analysis of the object appears as follows: (1) the object floats (2) the object floats (3) the object A just submerged
