浅析物体系的势能

Studies in Potential Energy of A System of Bodies

势能是物理学中的基本概念,本文将势能的两种定义法称为两种势能观。重点说明新势能观关于物体系势能的定义与计算,按新势能观,物体系可以是一个或多个物体。物体系的势能通常可以看作是内势能与外势能的总和。我国多数物理教材中所定义的物体系的势能,只相当于新势能观中的内势能。

Potential energy is a very basic concept in physics. In our article the two ways of definition of potential energy are called two kinds of potential energy viewpoint. The ditinition and the calculation of the potential energy of a body system is emphatically explained in a new potential energy viewpoint. According to the new viewpoint, the system may be one body ormany bodies. The potential energy of the system is usually regarded as summation of internal potential energy and extennal potential energy. In a majority of physics teaching materials of our country, what is defined as the potential of a bodysystem is merely an eguivalent of the internal potential energy of the potential energy viewpoint.
