狭义相对论中质量的严格定义
A rigorous definition of mass in special relativity
摘要:
经典力学中质量的公理化定义是由马赫在19世纪下半叶提出的,并经过几位作者的改进,被简化并推广到狭义相对论中。根据这里提出的扩展定义,相对论性粒子的质量与其速度无关,与静止质量一致,即,质量是经典力学定义的。然后,力被定义为质量和加速度的乘积,在经典和相对论的框架。
英文摘要:
The axiomatic definition of mass in classical mechanics, outlined by Mach in the second half of 19th century and improved by several authors, is simplified and extended to the theory of special relativity. According to the extended definition presented here, the mass of a relativistic particle is independent of its velocity and coincides with the rest mass, i.e., with the mass defined in classical mechanics. Then, force is defined as the product of mass and acceleration, both in the classical and in the relativistic framework.
