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

What is the equation for weight?

• Weight = mass / speed

• Weight = mass / gravity

• Weight = mass / volume

• Weight = mass / pounds

• True

• Sometimes

• False

• Never

What is Gravity?

• A force that makes us float

• An invisible force that keeps us on the ground

• An invisible force that rocks us
