中学物理学习过程中,经常需要将微小的物体或物理量进行放大,然后进行观察、测量。我在此谈谈高中物理常用到的放大方法。1.几何放大法几何放大法就是利用几何知识将某个物理量放大的方法。例如,根据圆柱体的体积公式V=Sh可知,相同的体积,横截面积越小,圆柱体越长,可以利用细管中液柱长度的变化来 Secondary school physics learning process, often need to be small objects or physical magnification, and then observe and measure. Here I am going to talk about the amplification methods commonly used in high school physics. Geometric magnification Geometric magnification is the use of geometric knowledge to a physical magnification method. For example, according to the cylinder volume formula V = Sh, we can see that the same volume, the smaller the cross-sectional area, the longer the cylinder, you can take advantage of the change in the length of the liquid column in the thin tube
