平抛运动是高考的重要内容之一.它的特点是物体以一定的初速度水平抛出,只受重力作用,是一类重要的匀变速曲线运动.在高中物理教材中,对于平抛运动问题的处理是利用运动的合成和分解的方法.将其等效地分解为水平方向的匀速直线运动和竖直方向的自由落体运动两个分运动,体现了解 The flat throwing movement is one of the important contents of the college entrance examination. Its characteristic is that the objects are thrown out at a certain initial speed level and are only affected by gravity. It is an important type of uniform variable speed curve movement. In high school physics textbooks, for the flat throwing movement The problem is dealt with by using the method of motion synthesis and decomposition. It is equivalently decomposed into a horizontal uniform linear motion and a vertical free-fall motion.
