Which statement is a scientific law?
A scientific law is a statement describing what always happens under certain conditions. Newton’s three laws of motion are examples of laws in physical science. A scientific law states what always happens but not why it happens. Scientific theories answer “why” questions.
What best describes a scientific law?
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 of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.
What statement describes a scientific theory?
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.
What are the 3 characteristics of a scientific theory?
A scientific theory should be:
- Testable: Theories can be supported through a series of scientific research projects or experiments. …
- Replicable: In other words, theories must also be able to be repeated by others. …
- Stable: Another characteristic of theories is that they must be stable. …
- Simple: A theory should be simple.

What is the scientific principle?
Principles are ideas based on scientific rules and laws that are generally accepted by scientists. They are fundamental truths that are the foundation for other studies. Principles are qualitative. … They are more like guiding ideas that scientists use to make predictions and develop new laws.

What are the four theories of law?
Though there are a number of theories, only four of them are dealt with here under. They are Natural, Positive, Marxist, and Realist Law theories. You may deal other theories in detail in your course on jurisprudence. Natural law theory is the earliest of all theories.
Who invented scientific method?
Sir Francis Bacon
Is gravity a law or a theory?
This is a law because it describes the force but makes not attempt to explain how the force works. A theory is an explanation of a natural phenomenon. Einstein’s General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.
What is a scientific theory example?
A scientific theory is a broad explanation that is widely accepted because it is supported by a great deal of evidence. Examples of theories in physical science include Dalton’s atomic theory, Einstein’s theory of gravity, and the kinetic theory of matter.
What makes a good scientific theory?
A good theory, like Newton’s theory of gravity, has unity, which means it consists of a limited number of problem-solving strategies that can be applied to a wide range of scientific circumstances. Another feature of a good theory is that it formed from a number of hypotheses that can be tested independently.
What is a good theory?
A good theory in the theoretical sense is (1) consistent with empirical observations; is (2) precise, (3) parsimonious, (4) explanatorily broad, and (5) falsifiable; and (6) promotes scientific progress (among others; Table 1.1).

What is scientific method and its characteristics?
The scientific method is the system used by scientists to explore data, generate and test hypotheses, develop new theories and confirm or reject earlier results.
