平衡状态是物体最基本、最简单的一种状态,在高中物理中我们主要研究共点力的平衡问题.共点力平衡问题的三角形解法是最直观、最快捷的一种解题方法,本文将就该方法做一简要的分析,希望给中学生提供一条清晰的解题思路.一、用力的三角形定性讨论三力平衡问题及求物解极体值受三
Balanced state is the most basic and simplest state of an object. In high school physics, we mainly study the balance of common point forces. The triangular solution to the point balance problem is the most intuitive and quickest way to solve problems. A brief analysis of the method will be provided in the hope of providing a clear problem-solving idea for middle school students. I. Qualitative discussion of the three-force balance problem and the solution of the polar body
