PHYSICS
Physics is that branch of science which deals with nature and natural phenomena.
The word 'physics' comes from the Greek 'knowledge of nature,' and in general, the field aims to analyze and understand the natural phenomena of the universe.
Physics covers a wide range of phenomena, from elementary particles (such as quarks, neutrinos, and electrons) to the largest super clusters of galaxies. Included in these phenomena are the most basic objects composing all other things. Therefore, physics is sometimes called the "fundamental science". The main goal of physics is to explain how things move in space & time and understand how the universe behaves. It studies matter, forces and their effects.
Physics aims to describe the various phenomena that occur in nature in terms of simpler phenomena. Thus, physics aims to both connect the things observable to humans to root causes, and then connect these causes together.
