WebThe gravitational equation says that the force of gravity is proportional to the product of the two masses (m 1 and m 2 ), and inversely proportional to the square of the distance (r) between their centers of mass. Mathematically speaking, F=Gm 1 m 2 / r 2 , where G is called the Gravitational Constant. WebMany people believe that the Moon’s gravitational force also affects humans, as our bodies are made up of approximately 70% fluid. However, there is no scientific evidence supporting this belief.
