What are the Main Branches of Physics

Science is an extraordinarily vast area of study that comprises different subjects and their branches. Each science subject has its importance in our day-to-day lives; there are three primary science subjects namely chemistry, biology, and physics.

Physics is one of the primitive science disciplines to be discovered and it involves the study of matter and its behavior along with energy and force.

It is a very vast subject that intersects with different subjects such as biophysics and quantum chemistry. The inventions in the field of physics have led to the rapid progress of physics in recent years. physics is a very important discipline that has led to the growth of modern technologies and thereby making our days to day lives simple.

 The Seven Main Branches of Physics

Many colleges and universities are now flooded with students pursuing physics majors; physics is a broad subject that offers many career opportunities. It has many branches and interdisciplinary subjects which include:

  1. Modern physics

Max plank and Albert Einstein are the pioneers of modern physics; it is a branch of physics that is primarily centered around relativity and quantum mechanics theories. These scientists were the first to propound the theory of quantum mechanics and relativity. Modern physics is the physics that comes after the era of 1900. Unlike other branches of s physics modern physics does not consider energy and matter as a single entity .at modern physics they are referred to as the two different forms of each other.

  1. Classical physics

Classical physics is among the most popular branches of physics that primarily deals with the different laws of motion and gravitation. This branch of physics majorly deals with matter and energy [ it can also be termed as physics which dates back from 1900 and before. this branch of physics was conceptualized by James Clark and Isaac newton. In this discipline, energy and matter are dealt with separately.

  1. Mechanical physics

Mechanical physics is a discipline that is more concerned with understanding the motion of material objects and the forces that influences them this discipline is divided into two main branches namely quantum mechanics and classical mechanics. quantum mechanics is primarily concerned with the behavior of small particles such as electrons while the other hand, classical mechanics studies the law of motion on physical objects and the forces that cause motion.

  1. Nuclear physics

Nuclear physics is a branch of physics that is concerned with the behavior, structure, constituents, and interactions of atomic nuclei. It differs from atomic physics as the latter deals with the study of atoms. In recent years nuclear physics has become a broad area s of study; more so the principles and theories of this branch can be used in various research and academic areas. nuclear physics can be applied in our daily lives such as in industries of medicine, magnetic resonance, imaging, and in the production of nuclear weapons.

  1. Atomic physics

This branch of physics is concerned with studying the composition of an atom apart from the nucleus. It is primarily concerned with understanding the behavior of electrons that are around the nucleus. Atomic physics moreover deals with the ions, electrons, and nuclei atoms. The recognition of matter is comprised of atoms is one of the forays of atomic physics .atomic physics led to the discovery of spectral lines which brought out an entirely new understanding of the structure of atoms and their arrangement.

  1. Acoustics

Acoustics is a physics sub-discipline that studies sounds; it majorly focuses on the mechanical waves passing through different forms such as liquids, solids, and gases. Moreover, acoustics studies vibration and focus on the transmission, control, reception, and effects of sounds.

  1. Optics

Optics on the other hand is an important branch of physics that studies light and its properties. Optics primarily studies the properties of light and its interaction with matter. Optics is further divided into physical and geometrical optics; geometrical optics focuses on the light interaction with mirrors and lenses while physical optics studies the nature of light and its other attributes.


Physics is one of the most important science domains; physics contributes largely to the current technological infrastructure. Moreover, physics enhances our understanding of earth, biological and chemical sciences; therefore physics is substantially important to all people in the world.

Physics discipline not only studies the objects under the action of the given force but also studies the nature of gravitational, nuclear, and electromagnetic forces. Today the field of physics has rapidly evolved and has further developed its own branches; which are broadly categorized as classical and modern physics.
