Definition: Effective mass

" Effective mass (Mᵉᶠᶠ) is a quasi-physical concept that explains how various forms of energy, such as dark energy and potential energy, influence gravitational dynamics and classical mechanics. When effective mass is negative, it is directly related to matter mass (Mᴍ): as the effective mass becomes more negative, the 'apparent' matter mass decreases. Conversely, as the magnitude of the negative effective mass increases (i.e., as Mᵉᶠᶠ becomes more negative), the kinetic energy increases; when the magnitude of the negative effective mass decreases (i.e., Mᵉᶠᶠ becomes less negative), the kinetic energy decreases, and vice versa.
