Bailee is incorrect in his explanation. The correct answer is B: Bailee's incorrect. The mass of the objects stays the same but weight will change.
Here's why:
- Mass is a measure of the amount of matter in an object and does not change regardless of location. An object's mass is the same on Earth, the Moon, or anywhere else in the universe.
- Weight is the force exerted by gravity on an object and is dependent on both the mass of the object and the gravitational pull acting on it. Since the gravitational pull on the Moon is about 1/6th that of Earth's, an object's weight would be less on the Moon, but its mass remains constant.
So, when Bailee talks about packing light, he should focus on how weight changes on the Moon, not the mass of his belongings.
