On the moon, the acceleration of gravity is 1.6 m/s2. If an object has a

mass on Earth of 5.1 kg, what is its mass on the moon?

5.1 kg

Explanation:

Its mass on the moon is 5.1 kg because mass is an intrinsic property of a material and does not change with location. Although, its weight might vary because its acceleration of gravity g is dependent on the mass M and radius r of the planet (in this case, moon) involved g = GM/r². Since weight W = mg is dependent o g, weight varies but mass remains constant.
