Source sentences:
text: This is nearly constant near the earth's surface because the mass and radius of the earth are essentially constant.
text: It follows that mass is constant for an object (actually this is not quite true as described by the Relativity Theory), but weight depends on the location of the object.
text: If the mass of the object is constant, this law implies that the acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object.
