For over 300 years, the formula for the force of gravitational interaction has been represented by the single law of universal gravitation of Newton. During this period, facts have been revealed that Newton's law of gravitation gives predictions that do not agree with observations. It is shown that Newton's law of gravity is not the single law of gravitational interaction in the Universe. Newton's law of universal gravitation (FN=GmM/r^2) is only one of three laws of gravitational interaction. In addition to Newton's law of gravitation, two new laws of gravitation are given: FK=mR^3/(T*r)^2; FCos=(mc^2)√Ʌ. These two laws of gravitational interaction remained undiscovered for more than 300 years. The three laws of gravitation (FN=GmM/r^2, FK=mR^3/(T*r)^2, FCos=(mc^2)√Ʌ) revive classical gravity and develop Newtonian dynamics towards a complete model of gravity. Newton's law of gravitation together with the two new laws of gravitation provide a complete and consistent description of gravitational interaction in the Universe.
