Answer: B) The law of gravity is one of several natural forces that explains and governs the motion of the planets and stars.
Explanation: Newton's law of gravity is a law that is not applicable only to the earth, but a law that is valid for the movement of celestial bodies (planets, stars, satellites, etc.), so it is a law applicable to the universe. According to this law, all celestial bodies move along certain paths, thanks to gravity in combination with the force of inertia. Thus, the position of all celestial bodies, for example in the solar system in terms of planets and natural satellites, is determined by their mass, size, etc., and their paths are determined by length and shape and where the planets never leave, precisely because of gravity and inertia .
