本章内容讲述了力与运动的关系,通过实验探究,认识牛顿第一定律,用物体的惯性解释自然办和生活中的有关现象;知道二力平衡条件。通过本章的学习,养成实事求是、尊重自然规律的科学态度,学会与他人交流与合作。一、主要知识点1.牛顿第一定律:(略)。2.惯性:(略)。3.惯性和牛顿第一定律的主要区别是:(1)物体的惯性不需要外加条件,是物体在任何情况下都具有的,而牛顿第一定律是有外加条件的,即:一切物体在没有受到外力作用;
This chapter describes the relationship between force and movement, through experimental exploration, understanding of Newton’s first law, the inertia of the object to explain the natural office and life-related phenomena; know the balance of power conditions. Through the study of this chapter, we should develop a scientific attitude of seeking truth from facts and respecting the laws of nature, and learn to communicate and cooperate with others. First, the main points of knowledge 1. Newton’s first law: (omitted). 2. Inertia: (omitted). 3. The main difference between inertia and Newton’s first law is that: (1) The inertia of the object does not require any external conditions and is the object has in any case, and Newton’s first law has the additional condition that all objects Not subject to external forces
