非惯性参照系中的机械能守恒

THE CONSERVATION OF MECHANICAL ENERGY IN NONINERTIAL SYSTEM

本文通过对某些惯性力是否有势的讨论,引入了惯性力势能的概念。从而把机械能守恒定律引入非惯性参照系,以较方便地解决实际问题。

Generally, to solve some dynamic problems in noninertial referencesystem is carried out by passing through solution of the dynamic equa-tion in the noninertial reference systems. However, the process to sol-ve the dynamic equation is usually more complicated. In this paper, ithas been discussed whether some inertia forces are conservative or not,and then, the concept of the potential energy of inertia forces and theconservation of mechanical energy have been introduced into the noniner-tial system. Thus, to resolve some dynamic problems in the system becomesmore simplified.
