inertsi
Inertsi is a term used in speculative physics and worldbuilding to denote a contextual measure of an object's resistance to changes in motion. Unlike classical mass, which is treated as an intrinsic property, inertsi is described as an effective inertia that depends on environmental factors such as a surrounding medium, electromagnetic or gravitational fields, relativistic effects, or the curvature of spacetime. Because of its contextual nature, inertsi is not a universally defined quantity and can vary between theories or authors.
Origin and usage: the word inertsi blends inertia with a suffix intended to indicate a property or
Measurement and interpretation: there is no standard unit or measurement procedure for inertsi. Values are typically
Applications and limitations: inertsi is most often encountered in thought experiments, theoretical discussions, or science fiction
