解决物理问题,归根结底是物理方法问题．教学中发现,尽管教材专门讲述了“力的分解”和“运动的分解”,学生对处理问题的方法也基本掌握,但遇到具体问题,需要分解其它矢量或分解其它运动形式时,有时仍显得无所适从．笔 Solving physical problems is, in the final analysis, a matter of physical methods. The teaching found that although the teaching materials specifically describe the “disintegration of forces” and the “disintegration of movements”, students basically grasp the methods of handling problems, but when they encounter specific problems, they need to decompose other vectors or decompose other forms of movement. It seems to be at a loss. pen
