Law of Gravitation Quiz

Which of the following statements best describes the Universal Law of Gravitation?

• It states that every object in the universe attracts every other object with a force proportional to their masses and inversely proportional to the square of the distance between them.

• It states that gravitational force is only applicable to celestial bodies.

• It states that gravitational force is independent of the distance between two objects.

• It states that gravitational force is proportional to the square of the distance between two objects.
