Abstract

Abstract. On the basis of the field ’ concept of gravitation and gravitational analogue of the Faraday’s induction law the difference of inertial mass of a body at its accelerated movement in horizontal and vertical directions relative to the Earth is shown. For an illustration of such a distinction the results of comparison of a motion of balance mechanical watch at horizontal and vertical orientations of balance ’ axis are given. The expediency of statement of precision me-chanical experiments with measurement of anisotropy of the inertial mass is noted, allowing to estimate the validity of the "field " approach in the description of gravitation.

    1. Alexander L. Dmitriev On the nature of inertial mass, Comments: 4 pages, 2 figures, Subjects: General Physics (physics.gen-ph)

        Abstract. It is shown that gravitational nature of inertial mass (Mach principle) agrees with idea of interaction of gravitational and electromagnetic forces and does not contradict the laws of classical mechanics. According to the simple phenomenological model the body inertial mass is directly proportional to its gravitational mass and the sum of coefficients, which characterize degrees of interaction of gravitational forces in accelerated motion of the body in accompanying and opposite directions relative to the gravitational force.

        Abstract. A brief review of experimental research of the influence of acceleration and temperatures of test mass upon gravitation force, executed between the 1990s and the beginning of 2000 is provided.Results of weighing a rotor of a mechanical gyroscope with a horizontal axis, an anisotropic crystal with the big difference of the speed of longitudinal acoustic waves, measurements of temperature dependence of weight of metal bars of non-magnetic materials, and also measurement of restitution coefficients at quasi-elastic impact of a steel ball about a massive plate are given.

All observably experimental effects, have probably a general physical reason connected with the weight change dependent upon acceleration of a body or at thermal movement of its microparticles.

        Abstract. The consistency of the results of measuring the gravitational force temperature dependence obtained by Shaw and Davy in 1923 and by the author in 2003 was shown. Such dependence is observed in the laboratory experiments, it does not contradict the known facts of classical mechanics and agrees with astrophysics data.

    Abstract. The experiment with weighing PZT-piezoelectric ceramics, heated up by a high-frequency signal for the temperature of 1.6 0‘ is briefly described. The negative change of piezoelectric ceramics weight having relative value of is confidently registered. The sign and the order of the value of relative temperature change of piezoelectric ceramics weight correspond to the measurements of weight of non-magnetic metal bars which were conducted earlier. What is emphasized as expedient for development of physics of gravitation is conducting similar measurements with use of various materials as samples and in a wide range of temperatures.

9. Alexander L. Dmitriev and Sophia A. Bulgakova The Negative Temperature Dependence of Gravity is a Reality

    Abstract-Temperature dependence of force of gravitation - one of fundamental problems of physics. This problem has got special value in connection with that the general theory of a relativity, supposing the weakest positive influence of a body temperature on its weight, actually rejects an opportunity of measurement of negative influence of temperature on a gravity in laboratory conditions. Really, the recognition of negative temperature dependence of gravitation, for example, means basic impossibility of achievement of a singularity ("a black hole") at a gravitational collapse. Laboratory experiments with exact weighing the heated up metal samples, indicating negative influence temperatures of bodies on their physical weight are described. Influence of mistakes of measurements is analyzed. Calculations of distribution of temperature in volume of the bar, agreed with experimental data of time dependence of weight of samples are executed. The physical substantiation of negative temperature dependence of weight of the bodies, based on correlation of acceleration at thermal movement of micro-particles of a body and its absolute temperature, are given.

    Abstract Weight (mass) of airtight container about 1.1 with electromechanical vibrator built-in inside, with independent supply and contactless control, has been measured. Decrease of container mass up to 170 , basically, is determined by heating of copper wire of vibrator electromagnet and practically is not related to artifacts - change of buoyancy, air convection, electromagnetic interference.

   Analogue of Lenz's rule in phenomenological gravitation

 Abstract
Analogies of the various physical phenomena for a long time are contributed to their understanding and progress of physical science. The basis of modern theories of gravitation is the equivalence principle, experimentally confirmed in experiments with slowly moving bodies. However, the physical situation changes in case of big accelerations of the bodies caused by external non-gravitational forces. Similarly to Lenz's rule, the force vec G of gravitation changes proportionally to value vec F of external force. Thus the sign of increment Δvec G is opposite to sign vec F, and the values of increments depend on orientation of vectors vec G and vec F. A consequence of it, for example, is the dependence of weight of a rotor of a mechanical gyroscope with a horizontal axis on angular speed of rotation, and also the temperature dependence of weight of bodies according to analysis of thermal movement of micro-particles. The gravitational analogy of Lenz's rule, on the basis of a Mach' principle, naturally explains proportionality of inertial and gravitational mass. The laboratory experiments confirming the above-stated ideas are briefly considered. Some astrophysical consequences of temperature dependence of force of the gravitation, agreed with observations are given. Opportunities of creation of new principles of propulsion by using the gravitational analogue of Lenz's rule are considered.

Measurements of the Influence of Acceleration and Temperature of Bodies on their Weight
A brief review of experimental research of the influence of acceleration and temperatures of test mass upon gravitation force, executed between the 1990s and the beginning of 2000 at the St.-Petersburg State University of Information Technologies, Mechanics and Optics in cooperation with D. I. Mendeleev's Institute of Metrology is provided. According to a phenomenological notion, the acceleration of a test mass caused by external action, for example electromagnetic forces, results in changes of the gravitational properties of this mass. Consequences are a dependence upon gravity on the size and sign of test mass acceleration, and also on its absolute temperature. Results of weighing a rotor of a mechanical gyroscope with a horizontal axis, an anisotropic crystal with the big difference of the speed of longitudinal acoustic waves, measurements of temperature dependence of weight of metal bars of nonmagnetic materials, and also measurement of restitution coefficients at quasi-elastic impact of a steel ball about a massive plate are given. In particular, a reduction of apparent mass of a horizontal rotor with relative size 3.10{sup -6} at a speed of rotation of 18.6 thousand rev/min was observed. A negative temperature dependence of the weight of a brass core with relative size near 5.10{sup -4} K{sup -1} at room temperature was measured; this temperature factor was found to be a maximum for light and elastic metals. All observably experimental effects, have probably a general physical reason connected with the weight change dependent upon acceleration of a body or at thermal movement of its microparticles. The reduction of mass at high temperatures is of particular interest for propulsion applications.
