一、教材分析(一)教材地位和作用“平抛运动”是人教版高中物理(必修2)第一章第二节的内容,在《普通高中物理课程标准》中《抛体运动》的内容标准为“会用运动合成与分解的方法分析抛体运动,能分别在水平方向和竖直方向建立直角坐标系,描绘抛体运动的物理规律”。平抛运动是一种最基本最重要的曲线运动,是运动的合成与 First, the textbook analysis (a) the status and role of teaching materials “flat cast sports ” is the PEP teaching physics (compulsory 2) the first chapter second section, in the “general high school physics curriculum standards” “The content of the standard ” will use motion synthesis and decomposition of the method of analysis of projectile motion, respectively, in the horizontal and vertical directions to establish a rectangular coordinate system, depicting the physical laws of projectile movement ". Ping throwing exercise is a kind of most basic and important curve movement, is the synthesis of movement
