A concise statement that describes a fundamental relationship in nature that has been repeatedly observed and tested, and is generally accepted to be true.

Here's why:

* Fundamental relationship: Scientific laws describe the underlying principles that govern how things work in the natural world.

* Repeatedly observed and tested: They are based on extensive experimental evidence and observations.

* Generally accepted to be true: While not absolute, they are widely accepted within the scientific community as accurate descriptions of how things behave.

Important distinctions:

* Not an explanation: Scientific laws describe what happens, not why it happens. Explanations are provided by scientific theories.

* Can be modified: Scientific laws can be modified or refined as new evidence emerges.

Examples:

* Newton's Law of Universal Gravitation: This law describes the force of attraction between any two objects with mass.

* Law of Conservation of Energy: This law states that energy cannot be created or destroyed, only transformed from one form to another.
