Newton’s law of universal gravitation says that the attractive force experienced by two objects is

• Directly proportional to the product of the masses of the objects

• Directly proportional to the distance between the centers of the two objects

• Inversely proportional to the product of the masses of the objects

• Only existent between heavy objects
