正确地对物体进行受力分析是学好物理的基本功,也是动力学总复习中需要着重强化训练的一项内容.笔者在复习教学中发现,不少学生对变力的特点难以把握,由此产生的失误与障碍也最多.为此,笔者引导学生就一些典型的变力的特点及相关问题的分析思路做了一个专题总结,有效提高了受力分析的训练成效.下面就将我们的专题总结介绍如下,供同行参考.
Correctly analyze the force of the object is to learn the basic skills of physics, but also the dynamics of the total review of the need to focus on strengthening the training of an author in the review of teaching found that many students are difficult to grasp the characteristics of change, resulting Of mistakes and obstacles are also the most.To this end, I guide students to some of the characteristics of typical variables and the analysis of related issues to do a special summary, effectively improve the effectiveness of the training analysis of force.We will summarize the following topics Introduced as follows, for peer reference.
