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.
Who is correct?

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.

Bella is correct because the moon exerts less gravity than the Earth.
Jackie is correct because weight and mass do not change based on the force of gravity.

The correct answer is: Bella is correct because the moon exerts less gravity than the Earth.
To understand why Bella is correct, we need to first understand the concepts of weight and mass. Weight is a measure of the force of gravity acting on an object, while mass is a measure of the amount of matter in an object. Weight is dependent on the gravitational force exerted by an object, while mass remains the same regardless of the gravitational force.
In this case, Bella correctly states that they would weigh less on the moon than on the Earth because the moon exerts less gravity than the Earth. This means that the force of gravity pulling on them would be weaker on the moon, resulting in a lower weight.
On the other hand, Sam is also correct when he says 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 gravitational force acting on it. So, even though their weight would be different on the moon, their mass would remain unchanged.
Jackie, on the other hand, is not correct in saying that her weight and mass would stay the same if she went to the moon. As previously explained, weight is dependent on the force of gravity, so it would be different on the moon. However, her mass would indeed remain the same.
In summary, Bella is correct in saying that they would weigh less on the moon due to its lower gravity, while their mass would stay the same.
