这一章讲授牛顿运动定律。牛顿运动定律在力学中占有重要地位,它是经典力学的基础。学好这一章,不仅有助于加深理解已学过的运动学知识,而且为进一步学习力学知识奠定基础。下面就这一的章改编情况作些说明。一、教学目的要求和单元划分这一章教材的目的要求是:掌握牛顿第一运动定律,明确力、惯性等概念的物理意义;正确理解和掌握牛顿第二定律;明确质量和重量的区别和联系;掌握力学单位制;了解超重和失重;会运用运动学公式、力的合成和分解以及牛顿运动定律分析解决综合性问题。这一章共分三个单元:第一单元(第一节)讲授牛顿第一定律、惯性和力;第二单元(第二节至
This chapter teaches Newton’s laws of motion. Newton’s law of motion occupies an important position in mechanics, and it is the basis of classical mechanics. Learning this chapter not only helps deepen the understanding of kinematics knowledge that has been learned, but also lays the foundation for further study of mechanics knowledge. Here’s a description of the chapter’s adaptation. First, the purpose of teaching requirements and unit division This chapter of the textbook’s purpose requirements are: to grasp Newton’s first law of motion, clear the physical meaning of the concept of force, inertia, etc.; correctly understand and grasp Newton’s second law; clearly the difference between quality and weight and Contact; master mechanical unit system; understand overweight and weightlessness; use kinematics formulas, force synthesis and decomposition, and Newton’s law of motion to solve comprehensive problems. This chapter is divided into three units: the first unit (Section 1) teaches Newton’s first law, inertia, and force; the second unit (Section 2)
