+**Mass** is a fundamental property of matter, a measure of its [Inertia](/wiki/inertia) – its resistance to changes in motion. It dictates an object's gravitational pull and its response to a [Force](/wiki/force), representing the amount of 'stuff' within it. This intrinsic quantity remains constant regardless of location.
