In Science, how do you differentiate law, theory and principle.?

Answer 1

A law is a proved theory
A theory is an idea of how it worx and
A principle is the rules that regulate that theory.

Answer 2

We often times try this to underscore what, precisely, a idea is. A idea isn't evidence of a few thing. that is a fashion to describe some phenomenon utilising lots of distinct experimental evidence that are all per that clarification. Theories will be disproven, and they can, and are, changed as we assemble further and extra evidence. The mechanism of gravity, the bending of area-time through remember, is unquestionably a idea with a number of unanswered questions. yet all the evidence we've signifies that mass does bend area time. Atomic structure is likewise a idea. no human being has ever considered an atom, yet we've a lot evidence that they contain a nucleus of protons and neutrons, with electrons spinning around the nucleus, we in simple terms take it as actuality. Evolution is a idea. It became no longer meant to describe how the first existence arose, yet what got here about afterwards. Darwinian evolution is between the most carefully examined theories in all of technology, and it withstood each project. The mechanisms underlying the approach are what we nonetheless have questions about. even if it should be common to disprove evolution, in simple terms through looking a fossil the position it doesn't belong. for instance, looking a fossil cat in Devonian age rock. To make a significant grievance of evolution through exclaiming that it ought to't clarify the first existence doesn't make experience. maximum scientists believe that the universe began from a singularity 15 billion years in the past. yet no you need to describe how that singularity got here into being, or what became there previously it. So do we throw out the most in many cases occurring idea for the beginning of the universe? Hell no! We in simple terms save digging. we've made amino acids and nucleotides spontaneously, besides as peptides and nucleic acids, the progression blocks of all existence. It took nature 500 million years after the earth cooled to produce the first existence, we've in undemanding words been attempting for the previous 50 years or so.

Answer 3

To answer your question, consider the law of gravity. The concept of "law" fits this force because it is universally proven to be true. This "law" pertains to our sun as well as the planets, and then also to ourselves. The unversality of a force or condition, when there is never a deviation from what is predicted, causes the concept of "law" to become established. Gravity is an always there kind of a thing, and it is a law.

Next, we come to a theory. A theory is a concept that needs acceptance in order to form into a law. The trilogy of physics E=mc2, m=E/c2, and c2=E/m describe all forms of energy/mass relationships in a general manner. Until the c2=E/m concept is proven by emperical evidence, (the formation and collapse of a gravitational field) and that evidence is accepted, it remains a theory.

Lastly, we come to the "principle" concept. To illustrate a principle, consider the gravitational values as one goes deeper and deeper into our planet. As a gravitational field continously becomes weaker and weaker the further one moves away from our planet, so, also, as one moves toward the very center of our planet the gravitational force increases. When at 0.716 miles from the very center of our planet, were a person able to release a mass there, the mass would, in one second accelerate to a speed greater that that of the speed of light. Within our sun the distance in 400 miles. The PRINCIPLE of acceleration determines that within our planet and sun there must exist masses there that are totally different from anything we know of, or there is a void space within the center of our planet that is about 1 and 1/2 miles in diameter, and our sun has one of almost 800 miles. This is information we gain by using a particular principle, that if correct, gives us insight into what we shall never be able to personally see.

Answer 4

a law is a theory that has stood the test of time

a theory is a principle that has been proven beyond a reasonable doubt and needs minor modification, but nonetheless is accepted as fact

a principle is a hypothesis or conjecture about how something might work (unproven unlike the other two) but based on observation

Answer 5

Answer 6

law is something that most occure.. like the law of gravity - what goes up must come down

theory is a hypothesis or an idea - if this happens then something else will happen but produces no real fact to be proven.

principle is THE idea

hope that helps

Answer 7

you read a science book and figure it out.
