Let us learn on "Definition of physics"
Physics is defined as the science of nature. It studies the quantity of matter a body contains and interactions between matter and energy in a wide variety of contexts. In other words, physics is basically the study of how objects behave.
The branch of science concerned with the study of properties and interactions of space, time, matter and energy.
Physics is considered to be the most basic of the natural sciences. It deals with the fundamental constituents of matter and their interactions as well as the nature of atoms and the build-up of molecules and condensed matter. It tries to give unified descriptions of the behavior of matter as well as of radiation, covering as many types of phenomena as possible. In some of its applications, it comes close to the classical areas of chemistry, and in others there is a clear connection to the phenomena traditionally studied by astronomers. Present trends are even pointing toward a closer approach of some areas of physics and microbiology.
