“机械运动”这一章中,有些知识点容易混淆,如参照物的选择、相对静止的条件、平均速度的概念等,同学们在学习的过程中会产生一些错误的认识.下面是对“机械运动”几个易错点进行分析,供同学们参考.易错点一:选择参照物或判断物体运动状态在选择参照物时,易把研究对象本身当做参照物,或者没有明确研究对象、没有理解运动的相对性,以致出错. “Mechanical movement ” This chapter, some knowledge points easily confused, such as the choice of reference objects, relatively static conditions, the concept of average speed, students in the learning process will produce some misunderstanding. Error analysis of a few easy points on the “mechanical movement” for the students to refer to .. Easy to make a mistake: a choice of reference objects or determine the state of objects in the choice of reference objects, it is easy to the study itself as a reference object, or not Clear research object, did not understand the relative nature of the movement, resulting in errors.
