静力学是高中物理板块的重要组成部分,是运动学和力学基础知识的首次融合。笔者整理、归纳了几种常见模型,对于求解静力学问题是很好的指引。一、斜面模型斜面是物理模型中最常见的形式之一,学生在分析问题时基本能做到灵活应用。例1如图1所示,质量为M的斜面静止于水平地面上,其倾角为θ。斜面上有一质量为m的小物块 Statics is an important part of high school physics and is the first fusion of kinematics and mechanics. The author arranges and summarizes several common models, for solving static problems is a good guide. First, the bevel model Bevel is one of the most common forms of physical model, the students can be flexible in the analysis of the basic application. Example 1 As shown in Figure 1, the slope of mass M is at rest on a horizontal ground with an inclination of θ. There is a mass on the bevel m small pieces
