    "abstract": "The axiomatic definition of mass in classical mechanics, outlined by Mach in\nthe second half of 19th century and improved by several authors, is simplified\nand extended to the theory of special relativity. According to the extended\ndefinition presented here, the mass of a relativistic particle is independent\nof its velocity and coincides with the rest mass, i.e., with the mass defined\nin classical mechanics. Then, force is defined as the product of mass and\nacceleration, both in the classical and in the relativistic framework.",
