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 ?
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.

Sam is correct because 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.

Sam is correct because 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. To understand why weight would be less on the moon, we need to understand the concept of gravity. Gravity is the force that pulls objects towards each other. The strength of gravity depends on the mass of the objects and the distance between them.

The moon has less mass than the Earth, so its gravitational force is weaker. This means that objects on the moon experience less gravitational pull compared to objects on Earth. As a result, if Jackie, Bella, and Sam were on the moon, they would weigh less than they do on Earth.

However, Sam is also correct in saying that their mass would be the same on the moon as it is on Earth. Mass is a measure of the amount of matter in an object and it remains the same regardless of the location or gravitational pull. So, whether they are on the moon or on Earth, Jackie, Bella, and Sam would have the same mass.

So, in summary, Bella is correct because they would weigh less on the moon due to its weaker gravity. Sam is also correct because their mass would remain the same on the moon. Jackie's statement is not correct, as weight does change based on the force of gravity.

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