Scientific laws describe patterns, not explain them.
* Example: Newton's Law of Universal Gravitation describes the attraction between any two objects with mass. It states that the force of attraction is proportional to the product of their masses and inversely proportional to the square of the distance between them.
* Key Point: This law doesn't explain *why* gravity exists. It simply describes the observed relationship between mass, distance, and gravitational force.
Scientific laws are based on empirical evidence and are considered universal.
* They are derived from repeated observations and experiments, and hold true across different situations and locations.
* Example: The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. This holds true in all known physical systems.
Scientific theories attempt to explain why these patterns exist.
* Example: Einstein's theory of General Relativity offers a more complete explanation of gravity, proposing that it's a result of the curvature of spacetime caused by massive objects.
* Key Point: Theories are more complex than laws and can be modified or replaced as new evidence emerges.
In summary:
* Scientific laws describe *what* happens.
* Scientific theories explain *why* it happens.
Think of it this way: Laws are like recipes, outlining the ingredients and steps to follow. Theories are like the science behind the recipe, explaining why those ingredients and steps work together to create a particular dish.
