Physics is the study of matter, energy, and the interaction between them. It seeks to understand the fundamental mechanisms of nature through observation, experimentation, and theoretical analysis. Physics is an ancient and broad field that has many branches including astrophysics, atomic and molecular physics, biophysics, condensed matter physics, cosmology, geophysics, mechanics, statistical mechanics, theoretical physics, and thermodynamics. Each branch studies a particular domain through the application of physical laws.

3. Physics(from Ancient Greek: φύσις physis "nature") is a natural science that involves the study of matter[1] and its motion through spacetime, as well as all related concepts, including energy and force.[2] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.[3][4][5]Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy.[6] Over the last two millenia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 16th century, the natural sciences emerged as unique research programs in their own right.[7] Certain research areas are interdisciplinary, such as mathematical physics and quantum chemistry, which means that the boundaries of physics are not rigidly defined. In the nineteenth and twentieth centuries physicalism emerged as a major unifying feature of the philosophy of science as physics provides fundamental explanations for every observed natural phenomenon. New ideas in physics often explain the fundamental mechanisms of other sciences, while opening to new research areas in mathematics and philosophy.Physics is also significant and influential through advances in its understanding that have translated into new technologies. For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.

4. AstrophysicsAstrophysics is the branch of astronomy that deals with the physics of the universe, including the physical properties (luminosity, density, temperature and chemical composition) of astronomical objects such as stars, galaxies, and the interstellar medium, as well as their interactions.

5. Atomic and molecular physicsAtomic and molecular physicsThe study of the structure and characteristics of atoms and molecules.

6. BiophysicsBiophysicsThe science of the application of the laws of physics to life processes.

7. Condensed-matter (solid-state) physicsCondensed-matter (solid-state) physicsThe study of the physical properties of solids, such as electrical, dielectric, elastic, and thermal properties, and their understanding in terms of fundamental physical laws.

8. CosmologyCosmology The study of the universe as a whole, of the contents, structure, and evolution of the universe from the beginning of time to the future.

9. GeophysicsGeophysicsthe study of the physical characteristics and properties of the earth; including geodesy, seismology, meteorology, oceanography, atmospheric electricity, terrestrial magnetism, and tidal phenomena.afterbefore

10. MechanicsMechanicsthe branch of physics concerned with the motion of bodies in a frame of reference.

11. Statistical MechanicsStatistical MechanicsThe discipline that attempts to relate the properties of macroscopic systems to their atomic and molecular constituents.

12. Theoretical physicsTheoretical physicsTheoretical physics attempts to understand the world by making a model of reality, used for rationalizing, explaining, and predicting physical phenomena through a “physical theory”.

13. ThermodynamicsThermodynamicsThe study of the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic scale by analyzing the collective motion of their particles using statistics.
