Theories and Theorems (Common Theories and Laws of Physics Explained)

Terminology is the study of terms and their uses. These are analysed from the point of view of their origin, formal structure, their meanings and functional features. Terms are used to denote concepts. This chapter presents the technical terms of science which have very specific meanings. It focuses only on those terms which give particular attention to the eBook content.

Physics is the scientific study of matter and energy. It ranges from subatomic particles to stars and entire galaxies. In experimental science, physics employs the scientific method to formulate and tests the facts based on observation of the natural world. A scientific principles, laws, theories and theorems describe the behaviour of how something occurs, why something works and the related method of mathematical reasoning. These are based upon observations and repeated experimentations. They can be disproved, modified or accommodate new discoveries and also they make predictions for future experiments and observations. This chapter presents the lists of important laws, theories and theorems of physics which describe, predict, and explain why, a range of phenomena behave as they appear to be in nature. This chapter also provides the basis upon which all of physics is based.

A hypothesis is not a prediction or guess. Testing is very important to prove that a hypothetical statement is hypothetical. Sometimes a hypothesis developed a new knowledge. Science proceeds by observation of nature. If hypothesis does not give any observational tests, nothing can be done by scientists. Only argument cannot make a law, theory and theorem. We can consider a hypothesis as an educated guess which must be testable and falsifiable. The scientific method has four steps: observations and description of a phenomenon, formulation of a hypothesis to explain the phenomenon, use of hypothesis to predict the existence of other phenomenon and several experimental tests of predictions. Experiment is only source to prove the truth. A hypothesis alone can teach us something new and alone can give us certainty; these cannot be questioned. This chapter shows the result of investigations and explanations for a phenomenon and a group of phenomenon.

This chapter pays little attention on how physics has given us a whole new point of view; physics behind a series of amazing facts. The definition of physics is not only associated with study of matter, energy and the interaction between them; but it is actually about to asking fundamental questions and try to answer them by observing and experimenting. This chapter includes few topics like: important ideas, legworks, important laws to remember, use of physics, role of physics and a theory of everything. This chapter also gives a look at what a world would be without physics.

Physics is not only the laws, theory and theorems; it is about to asking the fundamental questions and answering them by observing and experimenting. This chapter shows what physics is? How it works and why it is necessary to everyday life? Physics is concerned with understanding the world around us. One of the best ways to clarify our thinking about the visionary problems is through physics; to analyse ideas and arguments, to provide reasons and evidences for judgements and to explain. This area includes few topics like physics myths, why physics helps to understand world, how physics is useful to help others and few applications and examples with illustrations.
