laengutasakaaluga
Laengutasakaaluga is a term used in Estonian-language discussions to describe a hypothetical property in which a system's gravitational mass depends on the distribution of electric charge within it. The word is formed from laeng (charge) and kaal (weight), with the -uga suffix indicating 'with,' reflecting a proposed coupling between charge and weight.
In mainstream physics, the equivalence principle and mass–energy equivalence imply that gravitational mass includes all forms
Conceptual models of laengutasakaaluga often posit a coupling where the effective mass m_eff = m0 + f(Q) or
The term appears mainly in Estonian science communication, popular science writing, or science fiction contexts from
