The gravitational force is a fictitious force. Consider a test mass (m) taken to a distance (d) below the earth's surface, the acceleration due to gravity that point (gd) is obtained by taking the value of g in terms of density. At a fixed point on the surface, the magnitude of Earth's gravity results from combined effect of gravitation and the centrifugal force from Earth's rotation. The gravity of different planets is a function of planetary mass, radius and density. Since All are of Dimension L , the result of sum is also equal to L. How do we know acceleration due to gravity is 9.8 m/s 2? At a distance (d) below the earth's surface, the acceleration due to gravity is given by; g d = 4/3 (R - d) G.
