1、高一物理必修一知识点总结第一章运动的描述第一节认识运动机械运动：物体在空间中所处位置发生变化，这样的运动叫做机械运动。运动的特性：普遍性，永恒性，多样性参考系1.任何运动都是相对于某个参照物而言的，这个参照物称为参考系。2.参考系的选取是自由的。1)比较两个物体的运动必须选用同一参考系。2)参照物不一定静止，但被认为是静止的。质点1.在研究物体运动的过程中，如果物体的大小和形状在所研究问题中可以忽略是，把物体简化为一个点，认为物体的质量都集中在这个点上，这个点称为质点。2.质点条件：1)物体中各点的运动情况完全相同(物体做平动)2)物体的大小(线度)它通过的距离3.质点具有相对性，而不具有绝对

2、性。4.理想化模型：根据所研究问题的性质和需要，抓住问题中的主要因素，忽略其次要因素，建立一种理想化的模型，使复杂的问题得到简化。(为便于研究而建立的一种高度抽象的理想客体)第二节时间位移时间与时刻文档编码:CW5U9A5P8X6 HR6I7R8K2V7 ZW4B2G1R2K1文档编码:CW5U9A5P8X6 HR6I7R8K2V7 ZW4B2G1R2K1文档编码:CW5U9A5P8X6 HR6I7R8K2V7 ZW4B2G1R2K1文档编码:CW5U9A5P8X6 HR6I7R8K2V7 ZW4B2G1R2K1文档编码:CW5U9A5P8X6 HR6I7R8K2V7 ZW4B2G1R2K1文
