摘要
对经典力学的几个基本假设进行了较为详细的讨论,并提出了相应的不同假设。这几个假设是:认为匀速直线运动不存在,质点绕质心轴的匀速圆周运动是质点的惯性运动,建立在质心轴上的、描述这种匀速圆周运动的坐标系为该质点的惯性参考系,且惯性系是唯一的;牛顿第二定律与力的定义存在逻辑冲突,它反映的仅是两个质量悬殊的物体之间的作用力,故需要修正;惯性力是作用力,应当满足牛顿第三定律;质量的定义应回归为"物质的含有量",且质量具有相对性;万有引力定律也需要修正,所谓的引力常量G不是普适的常量,任一两体引力系统的引力系数应在1与2之间;质点的非惯性运动是其惯性运动以及所属质点系的惯性运动的叠加。
Several basic assumptions of classical mechanies were diseussed in detail and different assumptions were brought forward. These assumptions are as following: uniform rectilinear motion doesn' t exist, uniform circular motion of particle revolving centroid axis is inertia motion, coordinate system based on such centroid axis and motion is unique inertia reference system; Newton' s second law reflects force between two objects with huge different weights which has logical conflicts with the definition of foree and needs to be revised ; inertia force is an acting force which needs to meet Newton' s third law; concept of mass should be "matter' s contents" and mass has relativity; soealled gravitational constant G is not a generally applieable constant, and gravitational coefficient of gravitation system between two objects should be between 1 and 2 which means gravitational theory needs to be revised ; non - inertia motion of particle is the superposition of inertia motion and inertia motion of the whole system, etc..
