第一章牛顿运动定律这一章在复习必修课所讲内容的基础上,运用牛顿运动定律进一步分析和处理直线运动的力学问题.通过这一章的教学,应使学生清楚地理解运用牛顿运动定律处理力学问题的基本思路和方法,并能够按照这一基本思路和方法独立地分析和解决力学问题.这是本章教学的基本要求.完成这一要求,对学好其余力学知识以至整个选修课内容都有重要意义. 单元划分本章可分为三个单元: 1.第一单元:第一节,讲述同一直线上的矢量运算,属于预备知识. 2.第二单元;第二节至第四节,主要是复习必修课所讲内容. 3.第三单元:第五节、第六节,主要分析和研究物体在斜面上的运动以及连接体问题,是本章的重点. 最后一节介绍牛顿运动定律的适用范围,是选学
Chapter One Newton’s Law of Motion This chapter, based on reviewing the contents of compulsory courses, uses Newton’s laws of motion to further analyze and deal with the mechanical problems of linear motion. Through this chapter of teaching, students should clearly understand the use of Newtonian movement. The basic ideas and methods for dealing with mechanical problems and the ability to independently analyze and resolve mechanical problems in accordance with this basic idea and method. This is the basic requirement of teaching in this chapter. Completing this requirement will help you learn the remaining mechanics knowledge and the entire elective content. All have important meanings. Unit division This chapter can be divided into three units: 1. The first unit: The first section describes vector operations on the same line and belongs to preliminary knowledge. 2. The second unit; Sections 2 to 4 , mainly to review the required content of compulsory courses. 3. The third unit: Section 5, Section VI, mainly analyzes and studies the movement of objects on the slope and the problem of connecting bodies, is the focus of this chapter. The last section introduces the Newtonian movement. The scope of application of the law is selection
