A well-tested and widely accepted description of a natural phenomenon.
Here's why:
* Well-tested: Scientific laws are not just guesses or observations. They are based on extensive experimentation and data collection.
* Widely accepted: The scientific community must agree on the validity of a law before it is widely accepted.
* Description: Laws describe how things work in nature, not why they work that way. They don't explain the underlying mechanisms.
Examples of scientific laws:
* Newton's Law of Universal Gravitation: describes the force of attraction between any two objects with mass.
* Law of Conservation of Energy: states that energy cannot be created or destroyed, only transformed from one form to another.
* Law of Conservation of Mass: states that mass cannot be created or destroyed in ordinary chemical and physical changes.
