Accepted Answer

distance and mass

Answer

weight and time

Answer

area and weight

Question 11

The gravitational force exerted by an object depends on its

Accepted Answer

mass

Answer

volume

Answer

weight

Question 12

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

Accepted Answer

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

Answer

the apple weighs more than the bowling ball

Answer

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

Question 13

What is gravitational force?

Accepted Answer

The force of attraction between two objects.

Answer

It makes objects at rest start moving.

Answer

It makes objects that are moving stop.

Answer

It pulls you into space.

Question 14

As the product of two objects' masses increases, the pull of gravity

Accepted Answer

Increases

Answer

Decreases

Answer

Stays the same

Question 15

If a feather and a hammer are dropped at the same time on the moon, where there is no atmosphere, which one will hit the ground first?

Accepted Answer

both will hit at the same time

Answer

Neither, there is no gravity on the moon.

Answer

hammer because it has more mass

Answer

feather because it has less mass

Question 16

This FORCE pulls things. It PULLS things into orbit around the sun.

Accepted Answer

gravity

Answer

Answer

b. moon's mass is more

Answer

c. moon's mass is equal to Earth

Answer

d. moon has no mass

Question 18

Which of the following best describes gravitational force?

Accepted Answer

A force that acts between any two masses

Answer

A force that acts only on objects in motion

Answer

A force that acts only on objects with electric charge

Answer

A force that acts only at the surface of the Earth

Question 19

If the distance between two objects is doubled, how does the gravitational force between them change?

Accepted Answer

It becomes one-fourth as strong

Answer

It becomes four times stronger

Answer

It becomes twice as strong

Answer

It becomes half as strong
