A law can describe a phenomenon, and a theory can give a possible explanation for it.
|
|
|
A theory can state a simple guess, and a law can give more evidence to support it.
|
|
|
Scientists might not believe in scientific laws, but everyone believes in scientific theories.
|

A law has more hypotheses to test than a theory does.

Detailed explanation-1: -In general, a scientific law is the description of an observed phenomenon. It doesn’t explain why the phenomenon exists or what causes it. The explanation for a phenomenon is called a scientific theory.
Detailed explanation-2: -One major factor that a scientific hypothesis, theory, and law have in common is that they are all based on observations. A scientific observer observes a phenomenon and tries to explain what they observed. They form a hypothesis as a plausible explanation that can be tested for confirmational support.
Detailed explanation-3: -A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn’t, the theory is refined or rejected.
Detailed explanation-4: -A scientific law predicts the results of certain initial conditions. It might predict your unborn child’s possible hair colors, or how far a baseball travels when launched at a certain angle. In contrast, a theory tries to provide the most logical explanation about why things happen as they do.
