Abstract

Since Newton discovered the gravitation, the most direct and significant study of gravity is to measure the gravitational field of the earth, the gravitational field of the earth is indicated by the gravitational acceleration of the earth's surface, however, Newton's gravitational formula has not been able to describe accurately the gravitational acceleration of the earth's surface, and the gravitational acceleration calculated according to Newton's gravitational formula does not conform to the actual measured value of gravitational acceleration. In this paper using the new formula which describe the interaction between two matters to calculate the gravitational acceleration of the Earth, the calculated result is extremely agreement with the actual measured values.
