物理学中经常会涉及用圆的相关知识求解的问题,可以说物理与圆有着不解之缘.本文拟通过一些具体的实例,阐明圆在求解物理问题中的巧妙应用.一、等时圆何谓等时圆?我们先来看下面的例题:例1如图1所示,ad、bd、cd是竖直面内三根固 Physics often involves the use of circle related knowledge to solve the problem, it can be said that the physical and the circle have a bond .This paper intends to illustrate some of the practical application of the circle in solving physical problems by some specific examples. What is isochronous? Let us first look at the following example: Example 1 As shown in Figure 1, ad, bd, cd is vertical plane three solid
