Newton's Law of Universal Gravitation

What two things determine the gravity of an object?

• mass & weight

• mass & distance

• density & mass

• volume & distance

Which of the following will not change in different gravitational fields?

• weight
• force
• mass
• pounds

The amount of matter in an object is 

• pressure
• weight
• mass
• force

Which model has greater gravitational attraction (if any)

• Model A
• Model B
• Both Model A and Model B (same gravity)

As distance between two objects increase the pull of gravity 

• Increases
• Decreases
• Stays the same

When will the gravity between two objects be the LEAST?

• when the masses of both objects is small and the objects are close together

• when the masses of both objects is small and the objects are far apart

• when the masses of both objects is large and the objects are close together

• when the masses of both objects is large and the objects are far apart

Which statement about gravity is true?

• gravity causes objects to pull towards one another

• gravity causes objects to push away from each other

• gravity only takes place between planets

• the moon doesn't have any gravity

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity

If Earth's mass was cut in half, what would happen to your mass?

• increase because gravitational force increases
• decrease because gravitational force decreases
• decrease because gravitational force increases
• nothing, mass is not affected by gravitational force

Gravity attracts all objects towards one another.

• False
• True
• It depends
