标题： Kinetic Energy and the Equivalence Principle

摘要： 根据广义相对论理论，动能对引力质量有贡献。 令人惊讶的是，对于这一预测的观测证据似乎在文献中没有被讨论。 我重新分析现有的实验数据，以检验原子电子动能的等效原理，并表明可以得到相当严格的可能违反情况的限制。 我讨论这一结果与偶尔提出的“光以两倍于普通物质的加速度下落”的说法之间的关系。 显示英文摘要

摘要： According to the general theory of relativity, kinetic energy contributes to gravitational mass. Surprisingly, the observational evidence for this prediction does not seem to be discussed in the literature. I reanalyze existing experimental data to test the equivalence principle for the kinetic energy of atomic electrons, and show that fairly strong limits on possible violations can be obtained. I discuss the relationship of this result to the occasional claim that ``light falls with twice the acceleration of ordinary matter.''
