For more than 300 years, the formula for the force of gravitational interaction is represented by Newton's Uniform Law of Universal Gravitation. During this period the facts that Newton's law of gravitation gives predictions that do not agree with observations have been revealed. Here we show that Newton's law of gravitation is not the only law of gravitational interaction in the universe. In addition to Newton's law of gravitation, a new law of gravitation is obtained: FCos=(mc^2)√Ʌ. The two laws of gravitation (FN=GmM/r^2, FCos=(mc^2)√Ʌ) revitalize classical gravity and develop Newtonian dynamics towards a complete model of gravity. Newton's law of gravitation together with the new law of gravitation provide a complete and consistent description of the gravitational interaction in the universe. The real law of universal gravitation is presented in a new form. The law of universal gravitation is represented by two equivalent formulas: FU=GmM/r^2+(mc^2)√Ʌ; FU=mR^3/T^2*r^2+(mc^2)√Ʌ. The law of universal gravitation turned out to be much more complicated than Newton claimed.
