1. Weight:

Weight measures the gravity that pulls on the matter of an object.

Hence, the weight of an object on the moon will be different from that on the earth because of the difference of gravity between the two planets.

2. Mass:

Mass measures the amount of matter composing an object.

Hence, the mass of an object on the moon will stay the same with that on the earth because the object is still made up of the same amount of matter.
