In the present work, we have derived the formula for the variation of the gravitational constant given by G’=G/(1-v2/c2)-2 in very strong gravitational field of the compact bodies like super massive black holes and neutron stars applying special relativity and Newton’s law of gravitation for two bodies where v be the velocity of spinning compact bodies like black holes, neutron stars etc. and c be the velocity of light and calculated the variability of the gravitational constant (G) at different speed of the spinning of the black holes, neutron stars and quasars to show the speed is also factor governing the force of gravity addition to the mass.
