what is the exact definition of physics?

Question

please give in detail

Answer 1

Physics , ("nature" and "knowledge of nature") is the branch of science concerned with the fundamental laws of the Universe. It deals with the elementary constituents of the universe—matter, energy, space, and time—and their interactions.

Since antiquity, natural philosophers have sought to explain physical phenomena and the nature of matter, and this pursuit was formerly the study known as "physics" (once spelled physike, in imitation of Aristotle). The emergence of modern physics as a science distinct from natural philosophy began with the scientific revolution of the 16th and 17th centuries and continued through the dawn of modern physics in the early 20th century. The field has continued to expand, with a growing body of research leading to discoveries such as the Standard Model of fundamental particles and a detailed history of the universe, along with revolutionary new technologies like nuclear weapons and semiconductors. Research today progresses on a vast array of topics, including high-temperature superconductivity, quantum computing, the Higgs boson, and the attempt to develop a theory of quantum gravity. Firmly grounded in observations and experiments, with a rich set of theories expressed in elegant mathematics, physics has made a multitude of contributions to philosophy, science, and technology.

Discoveries in physics resonate throughout the natural sciences, and physics has been described as the "fundamental science" because other fields such as chemistry and biology investigate systems whose properties are based upon the laws of physics.[1] Chemistry, for example, is the science of substances formed by atoms and molecules in bulk, but the properties of chemical compounds are determined by the physical properties of their underlying molecules.

Experimental physics is closely related to engineering and technology. Physicists involved in basic research design and perform experiments with equipment such as particle accelerators and lasers, whereas physicists involved in applied research invent technologies such as magnetic resonance imaging (MRI) and transistors.

Theoretical physics is closely related to mathematics, which provides the language of physical theories, and physicists often rely on numerical analysis and computer simulations. The fields of mathematical and computational physics are active areas of research. Theoretical physics often relates to philosophy and metaphysics when it deals with speculative ideas like multidimensional spaces and parallel universes.

Answer 2

Physics is the systematic study of nature and natural phenomena.Since antiquity, natural philosophers have sought to explain physical phenomena and the nature of matter, and this pursuit was formerly the study known as "physics" (once spelled physike, in imitation of Aristotle

Answer 3

The branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms

Answer 4

Physics ("knowledge of nature") is the branch of science concerned with the fundamental laws of the Universe. It deals with the elementary constituents of the universe—matter, energy, space, and time—and their interactions.

Contemporary research in physics is divided into several distinct fields.

Condensed matter physics is concerned with how the properties of bulk matter, such as the ordinary solids and liquids we encounter in everyday life, arise from the properties and mutual interactions of the constituent atoms. A topic of current interest is high-temperature superconductivity.
Atomic, molecular, and optical physics deals with small numbers of atoms and molecules, particularly with how they interact with light. A topic of current interest is the behavior of Bose-Einstein condensates.
Particle physics, also known as "high-energy physics", is concerned with the properties of submicroscopic particles much smaller than atoms, including elementary particles such as electrons, photons, and quarks. A topic of current interest is the search for the Higgs boson.
Astrophysics and cosmology apply the laws of physics to explain celestial phenomena, including stellar dynamics, black holes, galaxies, and the big bang. A topic of current interest is determining the nature of dark matter and dark energy.
Since the twentieth century, the individual fields of physics have become increasingly specialized, and today most physicists work in a single field for their entire careers. "Universalists" such as Albert Einstein (1879–1955) and Lev Landau (1908–1968), who worked in multiple fields of physics, are now very rare.

Answer 5

Physics is the study of the fundamental laws and principles of nature.

Answer 6

PHYSICS
Physics (Greek: φύσις (phúsis), "nature" and φυσικῆ (phusiké), "knowledge of nature") is the branch of science concerned with the fundamental laws of the Universe. It deals with the elementary constituents of the universe—matter, energy, space, and time—and their interactions.

Answer 7

physics is the study of different forms of energy and its transformation. for example its the study of mechanical, sound, light, electrical energies. and its the science which tries to understand and analyse the statement "nature loves symmetry"

Answer 8

It's the science that tries to explain the natural phenomena, both qualitatively and quantitatively.

Answer 9

Measurement of physical properties of metal and non metal.

Answer 10

The study of the interaction of matter and energy.
