在高中阶段,速度的正交分解这一知识点经常应用在不同的运动情境中,如不同运动速度的两个或多个连结体运动的情景,运动物体的速度瞬间发生突变时的情景等.如果解题者稍有不慎,就会因不能正确的分解速度而造成失误.下面分析几道常出现速度分解的典型例题,以便更好地把握此知识点出现的规律性,达到灵活、准确应用的目的. In high school, the knowledge of orthogonal decomposition of speed is often used in different sports contexts, such as the movement of two or more connected bodies at different speeds, and the sudden change of the speed of a moving object. If the problem solver is slightly careless, it will cause mistakes due to the inability to correctly decompose the speed. The following analysis of several typical examples of speed decomposition often occurs, in order to better grasp the regularity of this knowledge, to achieve a flexible and accurate The purpose of the application.
