There are several theories that explain different aspects of our Universe. The single most important statement that physics makes (according to Feynmann) is the fact that matter is made up of atoms. Different parts of physics explain different aspects of the world; for example, quantum mechanics explains several important aspects.
explain how matter and energy are interrelated
nature
The objective of physics is to understand and explain the fundamental principles of nature by studying the interactions of matter and energy. It aims to provide a framework for predicting and explaining the behavior of physical systems, from the smallest particles to the largest galaxies. Ultimately, the goal of physics is to uncover the underlying laws that govern the universe.
the study of how energy and matter interact in the physical world
The known laws of chemistry and physics can explain the behavior of matter once it exists, but they do not specifically address the origin of matter. The Big Bang theory provides a scientific explanation for the origins of matter and the universe as a whole.
Some key science objectives in physics include understanding the fundamental forces of nature, exploring the origins and structure of the universe, investigating the behavior of matter at different scales, and developing theories that can explain and predict physical phenomena.
The simplest explanation is this: physics is the use of mathematics to help explain everything around us beginning with the laws of nature
The word 'physics' is a noun, a word for the science or study of nature and properties of matter and energy; a word for a concept; a word for a thing.
Nature Physics was created in 2005.
Physics is a branch of science which studies the nature and properties of matter. Electrons are constituent parts of matter and so their study is a part of physics. The behaviour of electrons is governed by mathematical rules and that is why mathematics is critical for electronics.
Based on the etymology of the word, physics can be defined in the following way: "Physics is the episteme of Nature, and Nature (Φύσις) is the phenomenon of spontaneous appearance and evolution." See Georgios Choudalakis' work on this at: http://www.mit.edu/~gchouda/miscellanea/physics/Physics_etymology.pdfBased on the etymology of the word, physics can be defined in the following way: "Physics is the episteme of Nature, and Nature (Φύσις) is the phenomenon of spontaneous appearance and evolution." See Georgios Choudalakis' work on this at: http://www.mit.edu/~gchouda/miscellanea/physics/Physics_etymology.pdf
The correct spelling of 'pysics' is physics. Physics is greek for knowledge of nature and is a part of natural science that involves the study of matter and its motion.
