引力是自然界的一种基本相互作用,地面物体所受的重力是引力在地球表面附近的一种表现。物体的重力是由于地球对它的引力而产生的,二者之间既密不可分可又存在着微小的差别,本文将从力的来源、方向、大小等方面来讨论分析重力与地球引力间的联系和微小差别。一、重力的来源将质量为m的物体放置在地球表面且相对地球静止,它受到两个力的作用,即地球的引力F_引和地
Gravitation is a basic interaction in nature. The gravitation of a surface object is a manifestation of gravitation near the surface of the earth. The gravity of an object is due to the gravitation of the earth. The two are not only inseparable but also have slight differences. This article will discuss the relationship between gravity and gravitation from the aspects of the source, direction and size of the force Contact and slight difference. First, the source of gravity will be mass m of the object placed on the surface of the Earth relative to the Earth and static, it is subject to two forces, that is, the Earth’s gravity
