You are unable to lift an object. Which property makes the object difficult to lift
The property that would make the object difficult to lift is its weight.
Bailee explained that when traveling to the moon, he needs to pack light because the weight of objects on the moon is the same as their weight on Earth. The mass of the objects is what changes when the gravitational pull changes. Is Bailee correct in his explanation?
No, Bailee is not correct in his explanation. The weight of an object is dependent on the gravitational pull acting upon it, so the weight would be different on the moon compared to Earth. However, the mass of an object remains the same regardless of the gravitational pull.
