• The mass of the other object would increase.

• The distance between the objects would increase.

• The gravitational force of the objects would remain constant.

Two basketballs are sitting 1 m apart and are not moving. Which best explains why the gravitational force does not cause them to move?

• No gravitational force exists between the two objects because they are not touching.

• The gravitational force between the two objects is weak because they are 1 m apart.

• No gravitational force exists between the two objects because their masses are small.

• The gravitational force between the two objects is weak because their masses are small.

If someone drops a cup, it falls to the ground. Why doesn't the gravitational force between the person's hand and the cup keep the cup from falling?

• The cup does not experience any gravitational force because it is not a planet.

• The gravitational force between the hand and the cup is so strong that it pushes the cup down.

• There is no gravitational force between the hand and the cup, so Earth's gravitational force pulls the cup down.

• There is a gravitational force between the hand and the cup, but Earth's gravity is stronger, so Earth's gravity pulls the cup down.

Which statement about a black hold describes why objects experience such a strong gravitational pull near a black hole?

• It has an extremely large mass and is much larger than the sun.

• It has an extremely small mass and is much smaller than the sun.

• It has an extremely large mass but is much smaller than the sun.

• It has an extremely small mass but is much larger than the sun.

A comet is orbiting the sun. How does the sun's gravitational force affect the comet during its orbit?

• It causes a continuous increase in the speed of the comet.

• It causes a continuous decrease in the speed of the comet.

• It causes the comet's speed to remain constant throughout its orbit.

• It causes the comet's speed to increase and decrease throughout its orbit.
