Abstract
Does mass depend on velocity? Is mass additive when bodies are joined? Is mass of an isolated system conserved? Sundry physics teachers and experts answer these questions differently because of disagreements on a definition of mass. We show that it is more rational to prefer relativistic mass dependent on velocity to rest mass.Download
