Mr. Gibson is trying to determine whether he would have a greater gravitational attraction to the moon or to the cat next to him on the couch. Which statement about Mr. Gibson's gravitational attraction is true? (SC.8. P.8.2)

She would have a greater gravitational attraction to her cat. Even though the cat contains less mass, she is much closer to the cat than the moon.

She would have a greater gravitational attraction to the moon. Even though the moon is much further away, it contains much more mass than a cat.

There is no gravitational attraction between Tina and the moon or Tina and the cat. The moon is too far and the cat doesn’t have enough mass.

There is equal gravitational attraction between Tina and the moon and Tina and the cat.

If Earth’s mass was cut in half, what would happen to your mass? (SC.8. P.8.2)

Nothing, mass is not affected by gravitational force.

Increase because gravitational force increases.

Decrease because gravitational force decreases.

Decrease because gravitational force increases.

On Earth, a brick has a mass of 10 kg and a weight of 5 lbs. What predictions could we make about the mass and weight of the brick on the Moon, where there is less gravity? (SC.8. P.8.2)

The weight of the brick could be less than 5lbs on the Moon.

The mass of the brick would be less than 10 kg on the Moon.

The mass of the brick would be greater than 10 kg on the Moon.

The weight of the brick could be greater than 5lbs on the Moon.

A 7 kg bowling ball on the Earth has a weight of approximately 15 lbs. Which of the following best represents the weight and mass of the same bowling ball on the moon. (SC.8. P.8.2)

The mass would remain the same but the weight would be less.

The mass would be less but the weight would remain the same.

The mass would become zero but the weight would be greater.

The mass would be greater but the weight would remain the same.

A television satellite is orbiting at a constant distance around Earth. Which of the following statements best describes the impact of gravity on the objects? (SC.8. P.8.2)

The gravitational pull of Earth is stronger than the gravitational pull of the satellite because larger objects in space have greater gravity.

The Earth and the satellite do not have any gravitational pull because no objects in space have gravity.

The gravitational pull of Earth and the satellite are the same because all objects in space have the same gravity.

The gravitational pull of the satellite is stronger than the gravitational pull of the Earth because smaller objects in space have greater gravity.

A student is given a sample of an unknown solid and asked to identify it. The student begins by making a list of questions to investigate about the sample. Which question would be the LEAST useful in helping the student identify the sample? SC.8.P.8.4

What is the weight of the sample?

Is the sample soluble in water?

Is the sample attracted to a magnet?

What is the melting point of the sample?

Your friend tells you the weight of a particular sample of chalk is 17.85 grams. Is there anything wrong with your friend’s statement? SC.8.P.8.2

Yes, because mass and weight are measured in different units.

Yes, because your friend should have reported the mass in Newtons.

No, because mass and weight are really the same thing.

No, because grams are the right units for weight.

Which action will change an object’s weight, but not its mass? SC.8.P.8.2

Placing the object on a different planet.

Compressing (squishing) the object.

Distillation is used to separate ______.

an insoluble solid from its solution.

a soluble solid from its solution.
