Integral form and application for the law of universal gravitation
Pan Yun-we · Journal of Science of Teachers' College and University · 2015
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.
