在理论力学的教科书中,有两处出现惯性力。一是在非惯性系动力学中,为使牛顿第二运动定律的数学表示式形式不变,引入惯性力;另一是在分析力学中的达朗伯原理,引入惯性力(为和上述惯性力加以区别,称达朗伯惯性力)。在现行的教科书中,认为惯性力是虚拟力(虚构的力)。在教学实践中,学生对两种惯性力的实质应如何理解?惯性力是虚拟力吗?多次提出疑问,本文试图谈谈作者的一点初浅看法。一、对力的概念认识应作历史分析人们对力的认识是在长期生产实践和科学实验中逐渐形成的。牛顿在前人研究、特别是
In the theoretical mechanics of textbooks, there are two inertia. First, in non-inertial dynamics, in order to make the mathematical formulation of Newton’s second law of motion constant, the introduction of inertial force; the other is the analysis of the principle of Darlung, the introduction of inertial force (for and inertia Force to distinguish, called Darlene’s inertia). In current textbooks, inertial forces are considered as virtual forces (fictional forces). In teaching practice, students should understand two kinds of essence of inertial force? Inertial force is a virtual force? Multiple questions, this article attempts to talk about the author’s point of view. First, the conceptual understanding of force should make a historical analysis of people’s understanding of force in the long-term production practices and scientific experiments gradually formed. Newton in previous studies, especially
