Question

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 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.

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.
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.

Answer 1

Jackie is correct because weight and mass do not change based on the force of gravity.

Answer 2

A person states that the gravitational force between two objects depends upon the mass of the objects and the distance between them. Which argument best supports the person’s statement?(1 point)
Responses

If the distance between two objects decreases, the gravitational force between the objects will not change.
If the distance between two objects decreases, the gravitational force between the objects will not change.

If the distance between two objects increases, the gravitational force between the objects will decrease.
If the distance between two objects increases, the gravitational force between the objects will decrease.

If the distance between two objects increases, the gravitational force between the objects will increase.
If the distance between two objects increases, the gravitational force between the objects will increase.

If the distance between two objects decreases, the gravitational force between the objects will decrease.

Answer 3

If the distance between two objects increases, the gravitational force between the objects will decrease.

Answer 4

When an astronaut is on a spacewalk and is moving away from the space shuttle, how does the force of gravity between the two objects change?(1 point)
Responses

it goes down
it goes down

it goes up for the astronaut and goes down for the space shuttle
it goes up for the astronaut and goes down for the space shuttle

it goes down for the astronaut and goes up for the space shuttle
it goes down for the astronaut and goes up for the space shuttle

it goes up

Answer 5

The force of gravity between the astronaut and the space shuttle decreases as the astronaut moves away from the space shuttle.

Answer 6

How does the gravitational force between Earth and the Moon change when the distance between the two objects doubles but mass doesn’t change?(1 point)
Responses

The gravitational force between Earth and the Moon would go down by a proportional amount.
The gravitational force between Earth and the Moon would go down by a proportional amount.

The gravitational force between Earth and the Moon would stay the same.
The gravitational force between Earth and the Moon would stay the same.

The gravitational force between Earth and the Moon would completely disappear.
The gravitational force between Earth and the Moon would completely disappear.

The gravitational force between Earth and the Moon would goes up by a proportional amount.

Answer 7

The gravitational force between Earth and the Moon would go down by a proportional amount.
