万有引力定律是基于质点这一理想模型所建立的,故将其应用于计算时通常要求施力物体和受力物体均可被视为质点。这既给实际物体所受万有引力的计算带来了困难,也难于满足理论认识的需要。通过对万有引力场和静电场进行类比分析,引入了引力强度和引力线的概念,提出了适用范围更广的万有引力定律的积分形式,并给出其相应的应用实例。

The law of universal gravitation is established based on the ideal model of particles,so an objects usually are required to be regarded as a particle when applying it for calculation.This not only causes the difficulty of calculation to real objects,but also can't meet the needs of the theoretical knowledge. It has carried on the gravitational field and electrostatic field analogy analysis,introduced the concept of the strength of gravity and gravity line,puts forward the integral form of the law of gravity which has more extensively applicable scope,and its corresponding application examples are given.
