Jackie, Bella, and Sam are discussing gravity. Bella says that they would weigh less on the moon than on the Earth ebcause the moon exerts lesss gravity than the Earth. Sam says that their mass would be he same on the moon as it is on Earth. Jack says that her weight and mass would stay the same if she went to the moon.
Bella is correct. Weight is dependent on the force of gravity, so if the moon exerts less gravity than the Earth, an object or person would weigh less on the moon. However, Sam and Jack are also correct in stating that mass remains the same wherever you go. Mass is a measure of the amount of matter in an object and does not change with location.
