1、高一物理必修一知识点总结整理第一章运动的描述第一节质点、参考系和坐标系质点定义：有质量而不计形状和大小的物质。参考系定义：用来作参考的物体。坐标系定义：在某一问题中确定坐标的方法，就是该问题所用的坐标系。第二节时间和位移时刻和时间间隔在表示时间的数轴上，时刻用点表示，时间间隔用线段表示。路程和位移路程物体运动轨迹的长度。位移表示物体（质点）的位置变化。从初位置到末位置作一条有向线段表示位移。矢量和标量矢量既有大小又有方向。标量只有大小没有方向。直线运动的位置和位移公式：x=x1-x2第二节运动快慢的描坐标与坐标的变化公式：t=t2-t1述速度量速度定义：用位移与发生这个位移所用时间的比值表示物

2、体运动的快慢。公式：v=x/At单位：米每秒（m/s）速度是矢量，既有大小，又有方向。速度的大小在数值上等于单位时间内物体位移的大小，速度的方向也就是物体运动的方向。平均速度和瞬时速度平均速度物体在时间间隔内的平均快慢程度。瞬时速度时间间隔非常非常小，在这个时间间隔内的平均速度。速率瞬时速度的大小。第四节实验：用打点计时器测速度电磁打点计时器电火花计时器练习使用打点计时器用打点计时器测量瞬时速度用图象表示速度速度一时间图像（v-t图象）：描述速度 v 与时间 t 关系的图象。第五节速度变加速度定义：速度的变化量与发生这一变文档编码:CS9Y10R7N8H5 HP4S6V2E2V9 ZP5M2F
