massM
MassM is a term used in certain scientific modeling contexts to describe a mass parameter that has been normalized to a reference mass. It is not a standard physical constant and is typically employed as a modeling convenience to facilitate comparisons across systems with different mass scales.
MassM is defined as massM = m / Mref, where m is the actual mass of interest and Mref
MassM is used to nondimensionalize equations of motion, energy, or other relations involving mass. This nondimensionalization
If m equals the reference mass, massM = 1. If m is twice the reference mass, massM = 2.
MassM relates to nondimensionalization, reduced mass in two-body problems, and other dimensionless parameters used to compare
