惯性是力学中的重要内容 ,而惯性概念的正确建立和有关惯性现象的解释是一个难点 ,因此在学习这方面知识时应注意领会以下几点 :1.正确理解惯性概念物体保持运动状态不变的性质叫惯性 ,对惯性应有如下的认识 :( 1)一切物体在任何时候、任何条件下都具有惯性。即无论物体是固体 Inertia is an important part of mechanics, and the correct establishment of inertial concepts and the interpretation of inertial phenomena is a difficult point. Therefore, when learning this knowledge, you should pay attention to the following points: 1. Correct understanding of the concept of inertia The nature of the property is called inertia. It should have the following understanding of inertia: (1) All objects have inertia at any time and under any conditions. That is, no matter if the object is solid
