矢量的分解在高中时一个很重要的解题前提,遵守平行四边形定则,而矢量力和速度的正交分解是重中之重,矢量的分解也是高中力学教学中必须使学生掌握好的一种技能。作为矢量的速度的分解,不是在任何力学问题中都能加以避免的,怎样能很好解决学生对此的一些困惑?我想就作为矢量的分解本 Vector decomposition in high school is a very important problem-solving premise, abiding by the rules of parallelogram, and orthogonal vector and velocity decomposition is the top priority, vector decomposition is also a high school teaching of mechanics must enable students to master a good Kind of skills. As a vector of speed decomposition, not in any mechanical problems can be avoided, how can we solve some of the students confusion? I think as a vector decomposition
