在教学过程中,发现现行统编教材中有些欠妥的地方(注一),现在提出来供同行们参考,共相探讨。 先提出以下观点作为立论依据: (一)一个已知力究竟该怎样分解呢?这就要具体考虑这个力产生的效果。(注二) (二)如果一个力作用在物体上,它产生的效果跟几个力共同作用的效果相同,这个力就叫做那几个力的合力,而那几个力就叫做这一个力的分力。(注三) In the course of teaching, I discovered that there are some defects in the current textbooks (Note 1), which are now proposed for reference by colleagues and discussed together. First put forward the following ideas as the basis for the argument: (A) How should a known force be decomposed? This requires concrete consideration of the effect of this force. (Note 2) (b) If a force acts on an object, the effect it produces has the same effect as several forces. This force is called the resultant force of those forces, and those forces are called the force. The force of the force. (Note 3)
