在《中学物理教学大纲》(90版)中,对简单连接体问题提出了明确的要求。以下谈谈加速度相同的简单连接体问题的解题体会。一、几点结论在解连接体问题时,一般都运用牛顿定律和隔离法.但对一些受力较简单的连接体,运用一些结论,能使解题过程极为简捷。1.匀强引力场中连接体例1 质量为 m_1、m_2两物体,用轻绳连接后,以相同的加速度竖直下落。
In the “Secondary Physics Teaching Syllabus” (90th edition), clear requirements are placed on the simple connector problem. Let’s talk about the problem-solving experience of the simple joint problem with the same acceleration. First, a few conclusions in the solution of the problem of connecting body, generally apply Newton’s law and isolation method. But for some connectors with simpler force, the use of some conclusions can make the problem-solving process extremely simple. 1. The connection method 1 in the uniform gravity field is mass m_1, m_2. After connecting with a light rope, it will fall vertically with the same acceleration.
