- A physical law or a law of physics is a statement
"Inferred from particular facts, applicable to a defined group or class of phenomena, and expressible by the statement that a particular phenomenon always occurs if certain conditions are present."
- Physical laws are typically conclusions based on repeated scientific experiments and observations over many years and which have become accepted universally within the scientific community.
- The production of a summary description of our environment in the form of such laws is a fundamental aim of science. These terms are not used the same way by all authors.
