  "definition": "Test Process that measures the quantity of matter which a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field. The term \u201cmass\u201d is always used in the strict Newtonian sense as a property intrinsic to matter. Mass is the proportionality constant between a force on a material object and its resulting acceleration. This property is sometimes referred to as \u201ctrue mass\u201d, \u201cvacuum mass\u201d, or \u201cmass in a vacuum\u201d to distinguish it from conventional [apparent] mass. The true quantity of matter represented in a vacuum with no gravitational force.",
