重量作为一个物理学概念,它的内涵究竟是什么?各教科书说法不一,对此有不同的定义,因而有不同的理解和解释。由于重量概念的不确定(主要反映在重量与重力的关系上),因此,教学上常常由于模棱两可,使学生无所适从。在日常生活中,又有不少人把重量与质量混为一谈。所以,笔者认为有必要研究重量概念的确定性。我们知道,对某一个物理现象,尽管可以从不同的角度去认识它,可以用不同的方法去揭示它的本质特性,但是,该物理现 What is the meaning of weight as a concept of physics? There are different definitions of textbooks. There are different definitions for this, and therefore there are different interpretations and explanations. Due to the uncertainty of the concept of weight (mainly reflected in the relationship between weight and gravity), teaching is often equivocal and confusing for students. In daily life, many people confuse weight and quality. Therefore, I think it is necessary to study the certainty of the weight concept. We know that for a certain physical phenomenon, although it can be understood from different perspectives, it can be used in different ways to reveal its essential characteristics, but the physical
