Physics is the branch of science that studies the nature of matter, energy, and spacetime at the most fundamental level. It provides a foundation for all the natural sciences and engineering disciplines.

Branches of Physics are as follows:

Production and properties of sound.

The application of the principles of physics to various fields of astronomy to determine the physical nature and the origin and development of solar system, stars, galaxies, and the universe as a whole

Basic theoretical and experimental research in planetary, atmospheric, magnetospheric, and solar physics.

Atomic Physics-the study of the structure, properties and behaviour of the atom. Molecular Physics-the examination of the structure, prosperities, and behaviour of molecules

The application of tools and techniques of physics in the study of living things and life processes

The use and understanding of matter in its condensed (liquid or solid) state, the examination of the physical properties of solid material

The study of extremely low temperature

The analysis of the relationship between electrical and magnetic forces.

The analysis of the relationship between electrical and magnetic forces.

Fluid Physics - the study of the behaviours and movement of liquids and gases. Aerodynamics-study of the behaviour of moving air and the forces that it produces.

Is the theory of gravitation, General relativity predicts novel effects relating to the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light.

The study of the earth and its atmospheres and waters using the principles of physics

Involved the protection of people who work with or near radiation.

The study of mathematical systems that stand for physical phenomena

It is the application of physics to medicine.

Concerned with the structure and properties of the atomic nucleus and with nuclear reaction and their applications

Optics-the study of the nature and behaviour and properties of elementary particles and Quantum optics is a field of research in physics, dealing with the application of quantum mechanics to phenomena involving light and its interactions with matter.

Particle physics is a branch of physics that studies the elementary constituents of matter and radiation, and the interactions between them. It is also called high energy physics, because many elementary particles do not occur under normal circumstances in nature, but can be created and detected during energetic collisions of other particles, as is done in particle accelerators.

The study of highly ionised gases-gases that have been separated into positively and negatively charged particles.

It is the mathematical and conceptual framework for contemporary elementary particle physics.

Thermodynamics-the study of heat as well as other forms of energy and of the conversion of energy from one form to another. Statistical mechanics- the discipline that attempts to relate the properties of macroscopic systems to their atomic and molecular constituents.
