Gravity

What two things determine the gravity of an object?

• mass & weight

• mass & distance

• density & mass

• volume & distance

When will the forces of gravity between two objects be the GREATEST?

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

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

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

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

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
