Final answer:
A scientific law is a concise statement that describes a generalized pattern in nature and is usually expressed as a mathematical equation, supported by evidence from repeated experiments and observations.
Step-by-step explanation:
According to the scientific method, a scientific law is a statement that describes a generalized pattern in nature and is supported by extensive scientific evidence and repeated experiments. A scientific law is often concise and may be articulated through a single mathematical equation. Scientific laws and theories both stem from tested hypotheses; however, where a law uses concise language to describe what happens in nature typically as a single action or relationship, a theory provides a detailed explanation of an entire group of related phenomena. For example, Newton's second law of motion, which can be summarized by the equation F = ma where F is force, m is mass, and a is acceleration, is considered a law because it consistently describes the relationship between these quantities in a simple and universally applicable manner.
