Noun
reduced mass (plural reduced masses)
(physics) Half of the harmonic mean of two given masses.
Disadvantages versus a traditional slug include lower muzzle momentum due to reduced mass, reduced damage due to smaller bullet diameter, and significantly higher per-unit cost. Source: Internet
The reduced mass in place of the electron mass is used since the electron and proton together orbit each other about a common centre of mass, and constitute a two-body problem to solve. Source: Internet
For hydrogen-1, hydrogen-2 ( deuterium ), and hydrogen-3 ( tritium ) the constant must be slightly modified to use the reduced mass of the system, rather than simply the mass of the electron. Source: Internet
Peak accelerations can be increased by designing the vehicle with a reduced mass, usually achieved by a reduction in the fuel load and tankage and associated structures, but obviously this reduces range, delta-v and burn time. Source: Internet
Spectroscopy In quantum mechanics the energy levels of electrons in atoms depend on the reduced mass of the system of electron and nucleus. Source: Internet
The reduced mass of the system in these equations is close to the mass of a single electron, but differs from it by a small amount about equal to the ratio of mass of the electron to the atomic nucleus. Source: Internet
