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.

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

To understand why Jackie is correct, we need to understand the concepts of weight and mass.
Weight is the force exerted on an object due to the gravitational pull of another object. It is measured in newtons. Mass, on the other hand, is the amount of matter in an object and is measured in kilograms.
The force of gravity is dependent on the mass of the two objects and the distance between them. The moon is much smaller than the Earth, so its gravitational force is weaker. This means that objects on the moon would indeed weigh less than they would on Earth. Bella is correct in stating that they would weigh less on the moon than on Earth.
However, Sam is also correct in stating that their mass would be the same on the moon as it is on Earth. Mass is an intrinsic property of an object and does not change based on the force of gravity or the location of the object. So, even though an object would weigh less on the moon due to the weaker gravitational pull, its mass remains the same.
Therefore, it is Jackie who is correct. The weight, which depends on gravity, would be different on the Moon, but the mass would remain the same.
