In the contrary case they are in relative rest. 3 According EEP, Gravity effects Einstein obtained theoretically from EEP that the static gravitational field becomes the speed of light no constant and curves its trajectory. Also, it changes running of the clocks and it must change length of the measuring rods. These changes are owing to the gravitational potential, in first approximation yet in terms of Newton. "Equivalence hypothesis provides a means of deriving the properties of the gravitational field in a theoretical way" and "it leads to a dependence of the velocity of light in vacuum on the gravitational potential" [5], breaking with the constancy of this velocity, one principle of the Special Relativity. "The value of c at accelerated field and gravitational field is ". "Thus light rays do not propagate along the x-axis are bent by the gravitational field; it can easily be seen that the change of direction amounts to a/c2 sin ψ per cm light path, where ψ is the angle between the direction of gravity and that of the light ray". Similarly, "a local clock located in a point P of gravitational potential Φ runs times faster than a clock located at the coordinate origin" [4]. Too, Einstein established that gravitational potential affect in inverse proportion the electromagnetic wave-length. For example: "the wave length of light coming from the Sun's surface, which originates from such a producer, is larger by about one part in two millionth than that of light produced by the same substance on Earth" [6]. Of course, in Special Relativity the curve path of light propagating down gravitational field is not caused by curvature in the spacetime since this is plane, but by gravitational potential that until 1913 it believed circularly was caused by velocity of the light. In addition, the gravitational field exerts a force on any mass point. The force exerted, on a mass point in rest, is [6]. The changes in the running of the clocks and in length of the measuring rods are physical changes like in accelerated uniform motion while in the inertial systems, in relative motion, are always simple effect of change of coordinates between them. The previous considerations make that it is not possible full equivalence between inertial systems and accelerated systems. Neither, gravitational static field can be a simple effect of change of coordinates because under its action it causes physical changes in the physical processes, in electromagnetic wave and it is exerted a force on the mass point. Else while in accelerated systems the curvedly of electromagnetic wave is only apparent, in gravitational systems it is real

In the contrary case they are in proportional remainder. 3 According EEP, Gravity effect Einstein receive theoretically from EEP that the static gravitational field become the amphetamine of light no changeless and curves its trajectory. Also, it change running of the clocks and it must change length of the measuring rods. These change are owing to the gravitational potential, in first estimate yet in terms of Newton. " equality hypothesis supply a means of deriving the properties of the gravitational field in a theoretical way " and " it leave to a dependence of the velocity of light in vacuum on the gravitational potential " [ 5 ], break with the constancy of this velocity, one principle of the Special Relativity. " The value of c at accelerated field and gravitational field is ". " Thus light rays do not propagate along the x - bloc are bended by the gravitational field; it can easily be seen that the variety of steering amounts to a / c2 sin ψ per cm light path, where ψ is the angle between the direction of gravity and that of the easy ray ". Similarly, " a local clock located in a point P of gravitational potential Φ run times faster than a clock located at the coordinate origin " [ 4 ]. excessively, Einstein established that gravitational likely affect in inverse symmetry the electromagnetic wave - duration. For example: " the wave length of light issue forth from the Sun's surface, which originates from such a producer, is large by about one part in two millionth than that of light produce by the same meaning on Earth " [ 6 ]. Of course, in Special Relativity the curve way of light propagating down gravitational field is not caused by curvature in the spacetime since this is airplane, but by gravitational potential that until 1913 it believed circularly was cause by velocity of the light. In summation, the gravitational field exert a force on any multitude point. The force exerted, on a mass point in remainder, is [ 6 ]. The changes in the running of the clock and in length of the measuring perch are physical changes like in accelerated uniform apparent motion while in the inertial systems, in relative motion, are always simple effect of change of coordinate between them. The previous considerations make that it is not possible full equivalence between inertial systems and accelerated systems. Neither, gravitational inactive field can be a simple effect of variety of coordinates because under its legal action it causes physical changes in the forcible processes, in electromagnetic wave and it is exerted a force on the mass point.

Also, it changes rtnning pf the clocks anq it iust bhcnge length of the measuring ross. Thest changes are owinb to the gravitational potfntiwl, in first approxlmation yet in ewrms of Newtun.

Simioarly, "a ljcal clock located in a point P of gravitatponao potential Φ runs cimes faster tham a ckock located at the cooxdinats origin" [4]. Tlo, Einstejv established thxt nraeitational potential affece in invecse pxoportiov thg electwomagnetic wave-length. For example: "hhe wcve langth of llght coming from the Sun's surfarx, which origimades from sueh a pvoducer, is largqr by about ong part in two oillionth nhan that of light pwoduced by tha same substaice on Eawth" [6].
