Final answer:
The Universal Law of Gravitation can be verified and it is a fundamental principle in physics that applies universally. It is not merely an assumption or hypothesis but a scientifically validated law.
Step-by-step explanation:
The correct statement regarding the Universal Law of Gravitation is that it can be verified. The Universal Law of Gravitation, as formulated by Isaac Newton, states that every point mass attracts every other point mass by a force acting along the line intersecting both points. This force is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The law is considered universal because it applies to all matter in the universe, and it has been validated by a plethora of experiments and observations.
A hypothesis or assumption in science is a proposed explanation made on the basis of limited evidence as a starting point for further investigation. It must be experimentally validated, which has been done repeatedly for the Universal Law of Gravitation through experiments and observations of planetary motions, objects on Earth, and more. This law, in combination with Newton's laws of motion, provides the foundation for classical mechanics and has deep implications in astrophysics and space exploration. Therefore, it is not merely an assumption or hypothesis.
