Abstract
This paper develops the approach to special relativity put forward by John S. Bell. The classical dynamics of an electron orbiting a nucleus in uniform motion is solved analytically and compared to numerical simulations for an accelerated nucleus. The relativistic phenomena of length contraction and time dilation are shown to result from the electric and magnetic forces on the electron when its motion is analyzed in a single frame of reference. The relevance of these results for understanding the theory of special relativity is discussed.
本文发展了约翰-贝尔(John S. Bell)提出的狭义相对论方法。本文对电子绕原子核匀速运动的经典动力学进行了分析求解,并与加速原子核的数值模拟进行了比较。当在单一参照系中分析电子的运动时,长度收缩和时间膨胀的相对论现象被证明是电子所受电场力和磁场力的结果。讨论了这些结果对于理解狭义相对论的意义。
期刊介绍:
The mission of the American Journal of Physics (AJP) is to publish articles on the educational and cultural aspects of physics that are useful, interesting, and accessible to a diverse audience of physics students, educators, and researchers. Our audience generally reads outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels.
