1、物理 人教版,第一章运动的描述匀变速直线运动,图1,正向匀速运动,静止,反向匀速,C,题组扣点深度思考,图2,B,题组扣点深度思考,位移,时间,速度,速度,速度,时间,加速度,加速度,位移的大小,正,负,题组扣点深度思考,AC,题组扣点深度思考,人,车,车,人,题组扣点深度思考,题组扣点深度思考,题组扣点深度思考,题组扣点深度思考,1一看“轴”:,2二看“线”:,3三看“斜率”:,4四看“面积” :,5五看“截距”:,6六看“特殊点”:,课堂探究考点突破,图3,D,课堂探究考点突破,课堂探究考点突破,1.xt图象、vt图象都不是物体运动的轨迹，图 象中各点的坐标值是x、v与t一一对应 2.xt

2、图象、vt图象的形状由x与t、v与t的函数关 系决定 3无论是xt图象还是vt图象，所描述的运动情 况都是直线运动,图4,B,课堂探究考点突破,课堂探究考点突破,1用图象解题可使解题过程简化，思路更清晰，而且比 解析法更巧妙、更灵活在有些情况下运用解析法可 能无能为力，但是图象法则会使你豁然开朗 2利用图象描述物理过程更直观物理过程可以用文字 表述，也可以用数学式表达，还可以用物理图象描 述如果能够用物理图象描述，一般来说会更直观且 容易理解,C,课堂探究考点突破,课堂探究考点突破,图5,BD,课堂探究考点突破,课堂探究考点突破,课堂探究考点突破,分析物体运动过程,画运动示意图,找两物体位移关
