Branches of Physics

The following is a list of the branches of physics and a brief description of each.

The study of physics is extensive and can be divided into several branches. Some of these branches are listed below:

  1. Classical Mechanics: This branch is concerned with the motion of bodies under the action of forces, including the particular case in which bodies move at a constant speed in a straight line (uniform linear motion) or at a regular rate in a circular path (uniform circular motion).
  2. Electricity and Magnetism: Electricity & Magnetism are two related aspects of nature that are difficult to separate. In the late 18th century, researchers Benjamin Franklin, Michael Faraday, and Charles Coulomb began to study electricity.
  3. Quantum Mechanics: Quantum mechanics is the branch of physics relating to the very small. It results in what may appear to be some extraordinary conclusions about the physical world. Atoms and subatomic particles do not exist with certainty at definite spatial locations and times.
  4. Optics: Optics is the study of light and its interactions with matter. It uses physical and mathematical models to describe light’s behavior in different situations, including reflection, refraction, etc.
  5. Atomic Physics: It focuses on studying matter and energy at these small scales. It deals with topics like subatomic particles and their interactions with each other and other forms of value—like atoms or molecules—and how they react to electromagnetic radiation.
  6. Nuclear Physics: Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions. Other forms of nuclear matter are also studied. Nuclear physics should not be confused with atomic physics, which studies the atom, including its electrons, protons, and neutrons.
  7. Cosmology and Astrophysics: Cosmology and astrophysics study the universe, which is everything we can see, including galaxies, moons, stars, planets, and solar systems.
  8. Mesoscopic Physics: Mesoscopic physics is a subfield of condensed matter physics that deals with materials of an intermediate length.
