A student drops a bowling ball and an apple from a third-story window. Both objects hit the ground at the same time. From the experiment, the student should conclude that

• the apple weighs more than the bowling ball

• more air friction is acting on the apple than on the bowling ball

• gravity pulls on both objects, causing them to fall at the same time.

Amanda weighs about 600 N on Earth, but would only weigh about 100 N on the Moon. Which BEST explains why Amanda would weigh less on the Moon than on Earth?

• The circumference of the Moon is smaller than Earth, therefore it has less gravity.

• The lack of air pressure on the Moon weakens the gravitational force of the Moon.

• The mass of the Moon is less than that of Earth, therefore it has a weaker gravitational force.

• shape

• mass

What is the relationship between mass and gravitational pull?

• Higer mass creates higher gravitational pull

• Lower mass creates higher gravitational pull

• Lower gravitational pull creates more mass

The gravitational force on an object on the surface of the Moon is 1/6 that of the gravitational force on the same object on the surface of Earth. Why is gravity acting on the object on the Moon less than the gravity acting on the object on Earth?

• because the distance from Earth to the object has increased

• because the mass of the Moon is less than the mass of Earth

• because Earth is rotating at a faster rate than the Moon is rotating.
