在高中《物理》第一册(必修)第5 4面中有一道习题,题目的内容是这样的:题目1 质量是2kg的物体,受到互成90°角的两个力的作用,这两个力都是1 4N ,这个物体产生的加速度的大小和方向是怎样的?图1在《教师教学用书》中对该题的解答过程值得商榷,其解答过程是这样的:原解析 根据
There is an exercise in the 54th face of Physics (Volume One) (required) in high school. The content of the title is as follows: Topic 1 The mass is a 2kg object and is subjected to two forces that form a 90° angle. The force is 1 4N. What is the magnitude and direction of the acceleration produced by this object? Figure 1 The answering process for this question in the “Teacher’s Teaching Book” is worth discussing. The answering process is as follows:
