Branches Of Physics

Branches Of Physics

Branches of physics are the subjects studied within the scope of physics. The subject physics can be defined as the branch of science which deals with the study of properties of matter and energy along with the interaction between them is undertaken. Physicists have divided the subject into various branches and each branch has acquired a title of a full subject in modern days. Physics is one of the most important subjects of all science, therefore the branches of science have evolved to understand each and every underlying aspect of the physical world.

Physics can be classified into various branches but classical physics is mainly concerned with energy and matter. The traditional branches of classical physics are Optics, Acoustics, Electromagnetics, and Classical mechanics. With the rapid development of physics, the scope of the subject is growing so large that it is not possible to cover physics under the above branches. A number of main branches of physics are discussed below.

Branches Of Physics Mechanics

Mechanics

Mechanics is the branch of physics which deals with the motion of an object without or with the reference of force. Mechanics can be further divided into two branches namely quantum mechanics and classical mechanics. Quantum mechanics deals with the behavior of smallest particles like neutrons, protons, and electrons, while classical mechanics is the branch that deals with laws of motion of forces and physical objects.

Branches Of Physics Optics

Optics

This branch of physics deals with the behavior, propagation, and properties of light. It can be simply described as the study of the behavior of infrared light, visible light, and ultraviolet.

Branches Of Physics Thermodynamics

Thermodynamics

Thermodynamics deals with the study of heat and its relation with work and energy. Thermodynamics also deals with the transmission of heat energy by means of convection, conduction, and radiation.

Branches Of Physics Electromagnetism

Electromagnetism

Electromagnetism deals with the study of electromagnetic force like electric fields, light, magnetic fields, etc. there are two aspects of electromagnetism which are “electricity” and “magnetism”.

Branches Of Physics Relativity

Relativity

This branch of physics deals with the theorem that was formulated by Albert Einstein. The theory of relativity states that space and time are relative and all the motion must be relative to a frame of reference.

Branches Of Physics Acoustic

Acoustic

Acoustic deals with the study of sound and its transmission, production, and effects. It mainly involves the mechanical waves in gases, liquids, and solids which includes vibration, sound, ultrasound, and infrasound.
