一、教学目标在讲解《牛顿第二定律》这一课中,从理论知识方面来说,首先要求学生能够掌握牛顿第二定律的概念,通过控制变量法来研究加速度、质量和力三者之间的关系,并学会用图像来进行数据分析和处理。除此之外,还要了解力学中基本的国际单位以及导出单位。从实践过程方面来说,采用实验教学法,让学生仔细观察实验过程,动手进行测量,根据实验结果来归纳物体加速度、质量与外力之间的关系,然后由教师引导学生更深入地理解牛顿第二定律, First, the teaching objectives In explaining “Newton’s second law” this lesson, from the theoretical knowledge, first of all require students to master the concept of Newton’s second law, by controlling the variable method to study the acceleration, quality and force of the three Between the relationship and learn to use the image data analysis and processing. In addition, we must also understand the basic mechanics of the international units and exporters. In terms of practical process, the experimental teaching method is adopted to enable students to carefully observe the experimental process and conduct hands-on measurements. Based on the experimental results, the relationship between acceleration, mass and external force is summarized. Students are then instructed to have a deeper understanding of Newtonian Second law
