摘要: 惯性是物理学中最基本的概念之一,也是学****物理学最早遇到的概念之一。这一极为普通和平凡的概念曾经引导许多物理学家深入思考和剖析,促进物理学重大进展,其中蕴涵着深刻的物理思想和丰富的物理学研究方法的教益,是培养学生科学地思考问题的能力非常有效的素材对经典力学范围内现行的惯性观提出了不同的看法,认为对于惯性要区分:个别对象的性质与存在的性质;保持某种状态的性质与改变某种状态的性质;物的动力学特性与审美性。物体受力在做加速运动的现象与物体处于静止或匀速直线运动状态受到惯性力的现象(或者说参照系受到力看到不受力的物体做加速运动的现象)是等效的。(没有接触任何物体时的物体加速度。)

Abstract: Inertia is one of the most basic concept in physics, but also to learn the concept of physics, one of the first encounter. The concept of a very ordinary and extraordinary number of physicists have been guided in-depth thinking and analysis of significant progress in the promotion of physics, which implies a profound physical ideas and a wealth of physics research methods, lessons learned, is to train students to think scientifically in power is very effective material, This paper puts forward a different viewpoint to current inertial view inside classical mechanics scope and claims that we should distinguish the property of an object of study from the property of existence,the property of keeping the kind of state from the property of changing the kinds of states,and that we should also focus our attention on the dynamic characteristic and the appreciation of the beauty of physical law. Object force is doing to accelerate the movement phenomena and objects at rest or a state of uniform linear motion inertial force of the phenomenon (or reference by the power of seeing objects do not force the phenomenon of acceleration) are equivalent. (No contact with any object when the object acceleration.)

惯性是经典力学中的一个基本概念,同时它又是人们日常生活中的一个基础性观念,并且惯性也是经常被物理学界讨论的一个话题。可是,尽管经典力学经过了漫长的时期,大部分的物理教师在此问题上还存在着很多的混乱性,本文试从几个方面对惯性进行了讨论,望引起大家的共识。
一、惯性的概念及影响
什么是惯性?惯性是什么?
一切物体总保持匀速直线运动状态或静止状态,直到有外力迫使它改变这种状态为止。
这就是牛顿第一定律。物
