Mass

Mass is a fundamental property of object|objects, quantification|quantifying the amount of matter they contain.

It is a measuring|measure of an object’s resistance to acceleration when a force is applied, often referred to as inertia. Mass also determines the strength of an object’s [gravity|gravitational attraction](gravity|gravitational attraction) to other objects with mass. Unlike weight, which can vary depending on gravity, mass is constant regardless position in space. In ../../../../slop/relationality/ai-generated-relationality/relationality-slop-2026-03-02/strata/physics, it is typically measured in grams and plays a crucial role in [Newtonian mechanics](Newtonian mechanics) and [Einstein’s theory of relativity](Einstein’s theory of relativity).
