Physics, science that deals with the structure of matter and therefore the interactions between the elemental constituents of the observable universe. within the broadest sense, physics (from the Greek physikos) cares about all aspects of nature on both the macroscopic and submicroscopic levels. Its scope of study encompasses not only the behavior of objects under the action of given forces but also the character and origin of gravitational, electromagnetic, and nuclear force fields. Its ultimate objective is that the formulation of a couple of comprehensive principles that compile and explain all such disparate phenomena.
Physics is that basic science. Until rather recent times physics and physics were used interchangeably for the science whose aim is that the discovery and formulation of the elemental laws of nature. because the modern sciences developed and have become increasingly specialized, physics came to denote that a part of physics is not included in astronomy, chemistry, geology, and engineering. Physics plays a crucial role altogether in the natural sciences, however, and everyone such fields have branches during which physical laws and measurements receive special emphasis, bearing such names as astrophysics, geophysics, biophysics, and even physics. Physics can, at the base, be defined because of the science of matter, motion, and energy. Its laws are typically expressed with economy and precision within the language of mathematics.
