    人教版新课标高中物理必修1质点参考系和坐标系教案2篇

    ①平动的物体一般可以看作质点做平动的物体,由于物体上各点的运动情况相同,可以用一个点代表整个物体的运动,在这种情况下,物体的大小、形状就无关紧要了,可以把整个物体当质点。例如:平直公路上行驶的汽车,车身上各部分的运动情况相同,当我们把汽车作为一个整体来研究它的运动的时候,就可以把汽车当作质点。当然,假如我们需要研究汽车轮胎的运动,由于轮胎上各部分运动情况不相同,那就不能把它看作质点了。要注意的是:同一物体在不同情况下有时可看质点,有时不可以看作质点,一列火车从北京开到上海,研究火车的运行的时间,可将火车看成质点,而火车过桥时,计算火车过桥的时间,不可以将火车看成质点。②有转动但转动为次要因素例如:研究地球公转时,可把地球看作质点;研究地球自转时,不能把地球看作质点。③物体的形状、大小可忽略再如:乒乓球旋转对球的运动的较大的影响,运动员在发球、击球时都要考虑,就不能把乒乓球简单看作质点。

    (创设实例:多媒体播放视频刘翔的110m栏。)1.提出问题:怎样定量(准确)人描述车或刘翔所在的位置?2.提示:你的描述必须能反映物体(或人)的运动特点(直线)、运动方向、各点之间的距离等因素。3.总结:①为了定量地描述物体的位置及位置的变化,需要在参考系上建立适当的坐标系。坐标系是在参考系的基础上抽象出来的概念,是抽象化的参考系。为了定量地描述物体的位置及位置的变化需要在参考系上建立适当的坐标系,如果物体在一维空间运动,即沿一条直线运动,只需建立直线坐标系,就能准确表达物体的位置;如果物体在二维空间运动,即在同一平面运动,就需要建立平面直角坐标系来描述物体的位置;当物体在三维空间运动时,则需要建立三维坐标系。①一维坐标:描述物体在一条直线上运动,即物体做一维运动时,可以以这条直线为x轴,在直线上规定原点、正方向和单位长度,建立直线坐标系。如图1-1-1所示,若某一物体运动到A点,此时它的位置坐标XA=3m,若它运动到B点,则此时它的坐标XB=-2m(“-”表示沿X轴负方向)。
