a description of a natural phenomenon or principle that invariably holds true under specific conditions and will occur under certain circumstances
a description of an observed phenomenon
a generalization based on observation
a mere statement of the way things happen to happen
a model of observed facts
an observed regularity in nature, and it embodies some degree of replication and some kind of prediction
a rule or a set of rules which generalizes the behavior of some phenomenon in nature
a short summary of a large body of experience that has been well verified by experiment and observation
a statement about the state of nature, e
a statement of an observed pattern of behavior of the world
a statement of fact meant to explain an action or set of actions such as the law of gravity
a statement that is true and valid for all times and all places in the known Universe
a statement that summarizes an observed pattern in nature
a verifiable fact that has been observed, and repeated, and therefore proven to be true
a very persistent observation, possibly (but not necessarily) of a mathematical relationship
A statement of an order or relation of phenomena that, so far as is known, is invariable under the given conditions.
A logical, mathematical statement describing a consistency that applies to all members of a broad class of phenomena when specific conditions are met. Examples of scientific laws: Faraday's Law of electromagnetic induction, Coulomb's Law of electrostatic attraction, Dalton's Law of partial pressures, Boyle's Gas Law.
a statement describing an observed regularity. Laws describe rather than explain. A law may be either quantitative (including measurement) or qualitative (general characteristics). It must describe evidence that has been gathered using acceptable scientific standards of reproducibility.
A scientific law, or empirical law, is a general principle that is very well supported by evidence such as experimental results and observational data. Typically scientific laws are limited sets of rules that have a well documented history for successfully predicting the outcomes of experiments and observations.
