Question 22

Kepler's discovery is classified as a Law.

Kepler's discovery that planets move in elliptical paths around the sun is a scientific Law, as it describes a consistent, universal pattern observed in planetary motion that has been confirmed through repeated observations.

A) Law

This option is correct because Kepler's findings represent a fundamental principle regarding planetary motion that consistently holds true under various conditions, which is the hallmark of a scientific Law.

B) Inference

This option is incorrect as an inference is a conclusion drawn from evidence rather than a direct statement of a consistent phenomenon. Kepler's discovery is not merely a conclusion but a definitive rule describing planetary motion.

C) Theory

This option is incorrect because a theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence. While Kepler's laws can contribute to theories about planetary motion, the laws themselves are not theories.

D) Hypothesis

This option is incorrect as a hypothesis is a testable statement or prediction that can be investigated. Kepler's laws are established facts rather than temporary propositions awaiting validation.

Conclusion

Kepler's discovery is definitively categorized as a Law due to its empirical consistency and universal applicability in explaining planetary orbits. In contrast, the other options—Inference, Theory, and Hypothesis—do not accurately represent the nature of Kepler's findings, which are rooted in observable and repeatable phenomena.
