Final answer:
The mass of a stone on the moon would be the same as on Earth because mass does not change with location. However, the weight would be different as it depends on the gravitational force at a given location.
Step-by-step explanation:
The question we're addressing is, on the moon's surface, where gravity is only about one-sixth of Earth gravity, which property of the stone would be the same as on Earth. The correct answer is a) The mass. This is because mass is a measure of the amount of matter in an object and does not change when the object's location changes. Weight, on the other hand, is a measure of the gravitational force exerted on an object and does depend on the object's location. Thus, on the Moon, the weight of an object is reduced to one sixth of what it would be on Earth, while its mass remains unchanged. For reference, weight measurements can be taken with a spring scale, which measures how much an object stretches a spring due to gravitational force.
