Jackie, Bella, and Sam are discussing gravity. Bella says that they would weigh less on the moon than on the Earth because the moon exerts less gravity than the Earth. Sam says that their mass would be the same on the moon as it is on Earth. Jackie says that her weight and mass would stay the same if she went to the moon.

Sam is correct because their mass would be the same on the moon as it is on Earth.
Sam is correct because their mass would be the same on the moon as it is on Earth.

Sam and Bella are BOTH correct because the moon exerts less gravity than the Earth AND their mass would be the same on the moon as it is on Earth.
Sam and Bella are BOTH correct because the moon exerts less gravity than the Earth AND their mass would be the same on the moon as it is on Earth.

Jackie is correct because weight and mass do not change based on the force of gravity.
Jackie is correct because weight and mass do not change based on the force of gravity.

Bella is correct because the moon exerts less gravity than the Earth.

Answer 1

The correct response is:

Sam and Bella are BOTH correct because the moon exerts less gravity than the Earth AND their mass would be the same on the moon as it is on Earth.

Explanation:

• Bella is correct that they would weigh less on the moon because the moon has weaker gravity than the Earth.
• Sam is correct that their mass remains constant regardless of location; mass does not change when moving from one celestial body to another.
• Jackie is incorrect because her weight would not stay the same; weight is the force exerted by gravity on an object and will decrease on the moon due to lower gravitational pull.
