Answer:
Mass remains the same while weight changes based on location.
Step-by-step explanation:
The true statement of all is that mass remains the same but weight varies from place to place based on location.
Mass is the amount of matter in a substance. This amount is the same any where on earth or in the universe since the same standard is used.
Weight is the vertical force on a body. It is usually the product of gravity and mass;
Weight = mass x acceleration due to gravity
Since gravity varies from place to place, weight will also vary.
