Different Types of Physics

What is Physics?

Physics is the most fundamental branch of physical science which deals with the study of matter and energy, and their relationship with each other. In other words, Physics is basically the study of how objects behave. Physics is an important and basic part of physical science. It is experimental science. Classical Physics and Modern Physics are two Major Types of Physics.

Types of Physics

The Main Branches of Physics are:

  • Classical Physics
  • Quantum Physics or Modern Physics

The classical Physics believes in a single nature, only the particle nature of matter. It provides the macroscopic vision of matter. It is based upon Newton’s laws of mechanics and Maxwell’s laws of electromagnetism.

Quantum Physics believes in dual nature, both particle and wave nature of matter. It provides a microscopic vision of matter.

It is based upon Planck’s quantum theory of light and De Broglie’s idea of matter-wave.In the practical field, The common Types of Physics are:
