“能用实例解释机械运动及其相对性”是物理中考考试大纲中的一项理解范畴的知识点,它的重要性不可忽视.本人在以往的教学中发现,同学们在上新课的时侯很容易上手,感觉很简单、都会、都懂,但是真正到解题时却出现了很多问题.要想疏通这部分知识,本人认为可以通过以下的方式进行:一、练火眼金睛知识点:1.机械运动:一个物体相对于另一个物体位置改变的过程.2.参照物:在判断一个物体是否运动时,被选
“Explain the movement of the machine and its relativity with the example ” It is a knowledge point in the physical examination syllabus to understand the category, its importance can not be ignored I found in the previous teaching, students in a new class When it is very easy to get started, I feel very simple, will know everything, but the real problem-solving there have been many problems.To clear this part of the knowledge, I think that can be carried out through the following ways: First, : 1 mechanical movement: the process of changing the position of one object relative to another object .2 reference object: when judging whether an object is moving or not, it is selected
