The correct answer is:
Sam is correct because their mass would be the same on the moon as it is on Earth.
Explanation:
- Bella is correct in saying that they would weigh less on the moon due to its weaker gravitational pull. Weight is the force of gravity acting on an object's mass, so it decreases with less gravity.
- Sam is correct in stating that their mass would remain the same on the moon as it is on Earth. Mass is a measure of the amount of matter in an object and does not change regardless of location.
- Jackie is incorrect because weight does change based on the force of gravity; it would be less on the moon.
So, while Bella points out that weight decreases, Sam accurately states that mass remains constant. Jackie’s assertion is incorrect regarding how weight changes with gravity.
