力学是初中物理学习中的重要内容,对于初中阶段的学生来讲,要学透、学好必须从一开始就打好基础。本文设计了一堂力学课,旨在引导学生了解力学的基本知识,为达到此目的,笔者制作了演示实验模型,配合多媒体进行演示,直观形象地让学生熟悉、了解力的概念、分类等知识。 Mechanics is an important part of junior high school physics study. For middle school students, it is necessary to learn thoroughly and learn well from the beginning to lay a good foundation. This paper designed a mechanics class designed to guide students to understand the basic mechanics, in order to achieve this goal, I produced a demonstration model, with multimedia presentation, visual image to make students familiar with the concept of power, classification and other knowledge.
