What changes depending on location in the universe, mass or weight. explain

Weight

Explanation:

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. The amount of matter in a material is a characteristic of a given object. But, the force of gravity that acts upon the object's mass depends of where the object is placed. For example, placed on Earth, some force is corroborated, but on the Moon, the force of gravity would be different because Moon has a different acceleration of gravity.
