2. Newton's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Newton's_laws_of_motion

   Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by ...

3. Multiple comparisons problem - Wikipedia

   en.wikipedia.org/wiki/Multiple_comparisons_problem

   The following table defines the possible outcomes when testing multiple null hypotheses. Suppose we have a number m of null hypotheses, denoted by: H 1, H 2, ..., H m. Using a statistical test, we reject the null hypothesis if the test is declared significant. We do not reject the null hypothesis if the test is non-significant.

4. Newton's law of universal gravitation - Wikipedia

   en.wikipedia.org/wiki/Newton's_law_of_universal...

   Coulomb's law has charge in place of mass and a different constant. Newton's law was later superseded by Albert Einstein 's theory of general relativity , but the universality of the gravitational constant is intact and the law still continues to be used as an excellent approximation of the effects of gravity in most applications.

5. Statistical hypothesis test - Wikipedia

   en.wikipedia.org/wiki/Statistical_hypothesis_test

   When the null hypothesis is predicted by theory, a more precise experiment will be a more severe test of the underlying theory. When the null hypothesis defaults to "no difference" or "no effect", a more precise experiment is a less severe test of the theory that motivated performing the experiment. [4]

6. Hypothesis - Wikipedia

   en.wikipedia.org/wiki/Hypothesis

   A hypothesis (pl.: hypotheses) is a proposed explanation for a phenomenon. A scientific hypothesis must be based on observations and make a testable and reproducible prediction about reality , in a process beginning with an educated guess or thought.

7. Scientific method - Wikipedia

   en.wikipedia.org/wiki/Scientific_method

   The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...

9. Boyle's law - Wikipedia

   en.wikipedia.org/wiki/Boyle's_law

   Instead of a static theory, a kinetic theory is needed, which was developed over the next two centuries by Daniel Bernoulli (1738) and more fully by Rudolf Clausius (1857), Maxwell and Boltzmann. This law was the first physical law to be expressed in the form of an equation describing the dependence of two variable quantities. [10]
