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 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. Weight is determined by the force of gravity acting on an object, while mass is a measure of the amount of matter in an object. The force of gravity may vary depending on the celestial body, but the mass remains constant.
To understand this concept, we need to first understand what weight and mass are. Weight is the force exerted on an object due to gravity. It is calculated by multiplying an object's mass by the acceleration due to gravity. On Earth, this acceleration is approximately 9.8 m/s². Mass, on the other hand, is the measure of the amount of matter in an object. It is a fundamental property of an object and does not change.
Now, let's apply this understanding to the situation. Bella suggests that they would weigh less on the moon because the moon exerts less gravity than the Earth. This statement is correct. The strength of gravity on the moon is about 1/6th of that on Earth. Therefore, if they were on the moon, their weight would indeed be less compared to what it would be on Earth.
However, Sam also makes a correct statement. 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 remains constant regardless of its location. So, even if they go to the moon, their mass would remain the same.
Ultimately, Jackie is correct because weight and mass are independent of the force of gravity. Their weight would change on the moon, but their mass would stay the same.
