处理抛体问题的新视角

A New View of Parabolic Motion

传统教学中,我们都是利用抛体运动的运动方程来讨论其运动的一般规律,而用演绎的方法把平抛运动作为一种特殊的抛体运动来处理,本文将从平抛运动出发,来处理一般抛体的问题,旨在为分析抛体问题开拓一种新的思路.

In traditional teaching of parabolic motion, we used to translate it into horizontal direction and vertical direction motions. Teachers also emphasize this method extremely , so that students practice it repeatedly. It makes that many students have wrong understanding： Translation is the only method of resloving parabolic motion. How to correct this wrong idea ？ In fact, we may use tevel parabolic motion to discuss general parabolic motion, and our aim is to seek a kind of new way of parabolic motion.
