What are the differences between scientific hypotheses scientific theories and scientific laws.?

Answer 1

A hypothesis or a theory is a question or problem posed and is answered or attempted to be answered by a scientific method of experimentation. A theory is a tested and accepted principle or proposition i.e. quantum theory, Occam's Razor, Newton's law of gravity. A law is a theory that withstands the test of time.

Answer 2

Laws exist in nature and can be discovered.

Theories are attempts to explain something (such as the behavior of something in a specific situation)

Hypotheses are suggestions which hopefully can be tested and if proved correct could become theory.

Answer 3

A belief is an act of faith. E.g. I believe in God. or I believe that Santa will deliver. Scientists do not consider beliefs as having anything to do with Science. There are many scientists who have personal beliefs, but they are outside the realm of science.

A hypothesis is a proposal intended to explain certain facts or observation. I.e. its your explanation on why something will happen. E.g. My drink gets cold when I dip it in ice water. My hypothesis is that the can is warmer than the ice and when I put it in the ice, the heat of the can actually warms the ice, and in the process it becomes colder.

A scientific law or scientific principle is a concise verbal or mathematical statement of a relation that expresses a fundamental principle of science, like Newton's law of universal gravitation. A scientific law must always apply under the same conditions, and implies a causal relationship between its elements. The law must be confirmed and broadly agreed upon through the process of inductive reasoning.

In the sciences, a scientific theory comprises a collection of concepts, including abstractions of observable phenomena expressed as quantifiable properties, together with rules (called scientific laws) that express relationships between observations of such concepts

In the sciences the definition of Theory is very different than in ordinary usage, where a theory is a proposal to explain something. This is more accurately a hypothesis, but we call it theory.

A law differs from a scientific theory in that it does not posit a mechanism or explanation of phenomena. In science a Theory is actually a very well thought out and researched set of concepts. For something to be called a Scientific Theory it must have stood the test of time. One of the most famous and controversial theories is the Theory of Evolution.

Answer 4

scientific hypothyses are educated guesses on something.

scientific theories are hypothesis that cant be tested.

scientic laws are hypotheis that have been tested and proven to be 100% true.

Answer 5

An hypothesis is an idea which is put forward to try to explain our observations. We usually test the hypothesis with an experiment. A theory is a set of ideas which is successful at explaining those observations and is, ideally, supported by experiment. The line between a well accepted theory and a Law is mutable, but the term law is usually reserved for a specific, usually mathematical, relationship. For instance, Boyle's Law (about gases) is stated as PV is a constant. We use the kinetic theory to explain it.

Answer 6

A hypothesis is an educated guess about how things work.
In science, a hypothesis is an idea or explanation and then you then test by study and experimentation.
A law is a system of rules that are enforced through institutions to govern behavior. If you go over the speed limit, you have broken the law.
The word law in science is the description of an what is seen. It doesn't explain why the phenomenon exists or what causes it. The law of gravity is an example of a law in science. For a very long time no one understood what made it happen.
Most people use the word 'theory' to mean an idea or hunch that someone has.
But in science the word 'theory' works this way:
1. Start with an idea (hypothesis)
2. Do some experiments
3. Do the experiments is support the idea? No? then a bad idea
4. Yes! then theory is created
5. Get more information to better understand
6. Discover even more information
7. Modify theory
8. Does modification explain the idea? No? End of theory.
9. Yes? Explain the new evidence?
10. Improve the theory.

Answer 7

Laws are confirmed, validated hypotheses and theories.

Answer 8

From a scientific hypothesis a scientific theory can be developped after experiments; this theory can contain scientific laws.
