摘要

研究考虑了复合物体(如核子、原子核、原子和分子)在其构成部分快速内部运动时的引力质量和惯性质量之间的联系。只要其运动的构成部分是封闭的,就能证明这些物体的引力质量和惯性质量相等,证实了弱等效原理。由于非惯性框架中的粒子动力学与引力场中的粒子动力学之间存在很大差异,因此结果非常不简单。矛盾的是,同样的粒子在封闭箱中运动和在自由空间中运动,引力效应是不同的。引力质量和惯性质量等于相应的运动质量。相反,不能引入非相互作用运动粒子集合体的引力质量,因为作用在这些集合体上的总引力与其运动质量不一致。

Connection between gravitational and inertial masses of compound objects and the weak equivalence principle
The connection between gravitational and inertial masses of compound objects (e.g. nucleons, nuclei, atoms, and molecules) in the presence of rapid internal motions of their constituent parts is considered. The equality of gravitational and inertial masses of such objects confirming the weak equivalence principle is proven provided that their moving constituent parts are confined. The result is very nontrivial because of a substantial difference between particle dynamics in noninertial frames and gravitational fields. Paradoxically, gravitational effects are different for the same particles moving in the closed box and in the free space. The gravitational and inertial masses are equal to the corresponding kinematic masses. In contrast, gravitational masses of ensembles of noninteracting moving particles cannot be introduced because the total gravitational forces acting on these ensembles do not correspond to their kinematic masses.
