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.

The correct answer is: Jackie is correct because weight and mass do not change based on the force of gravity.
To understand why Jackie's statement is correct, it's important to first differentiate between weight and mass:
- Mass: Mass is a measure of the amount of matter in an object. It is a fundamental property of an object and does not change regardless of the location. In other words, an object will have the same mass whether it is on Earth, the moon, or anywhere else in the universe.
- Weight: Weight, on the other hand, is the force exerted on an object due to gravity. Weight is dependent on both the mass of an object and the gravitational force acting on it. The force of gravity is stronger on Earth than on the moon because Earth has a larger mass. Therefore, an object will weigh less on the moon than on Earth due to the weaker gravitational force.
In this scenario, Jackie is correct because weight is influenced by the force of gravity, not mass. Regardless of whether they are on Earth or the moon, the mass of Jackie, Bella, and Sam would remain the same. However, since the moon exerts less gravity than Earth, their weight would be less on the moon.
