平抛运动是较为复杂的匀变速曲线运动,有关平抛运动的命题层出不穷,若能切实掌握并有应用一些有用的结论,就不难解决平抛问题了,针对平时所遇到的问题及高考的命题趋势。为此,我对平抛运动中的两个有用结论进行了证明和总结,来帮助学生提高解决问题的能力。平抛运动用了“变曲为直”的思想,即水平方向做匀速直线运动,竖直方向做匀加速直线运动。规律如下: Ping throwing is a more complex movement of uniform speed curve, flat throwing motion propositions emerge in an endless stream, if we can effectively grasp and apply some useful conclusions, it is not difficult to solve the problem of flat throw, for the usual problems encountered and the college entrance examination Proposition trend. To this end, I have demonstrated and summarized two useful conclusions from the Pingtan campaign to help students improve their problem-solving skills. Ping throwing movement with “change to straight ” idea that the horizontal direction to do uniform linear motion, the vertical direction to do uniform acceleration linear motion. The rules are as follows:
