Physics Theories - Branches and Laws with Respective Fields

List of Basic Physics Relations - Class 11 and Class 12

Physics contains a wide range of ideas and equations. Also, everything we know about the physical world can be summarised in just five theories, which deserve to be called the great theories of Physics. Each theory is a framework of ideas and equations that have been tested and proven by experiments. The scientific community is constantly validating these theories over time. In this article, we’ll discuss the Physics theories, how many types of Physics fields are categorised, and what are the main branches of Physics.

Advantages of Learning Laws and Branches of Physics with Examples

Physics is one of the natural science disciplines that study the different aspects of matter and energy. By understanding Physics theory, its laws and branches with examples we will understand mechanics, electricity, magnetism, heat, sound, light and other radiation, and the structure of atoms which are the major topics in this discipline. Also, Physics theories explain the evolution, structure, and functions of various universe elements.

Physics is a broad field of scientific study that includes various concepts, principles, and theories. We have discussed some of the important branches and laws of Physics that a student should be familiar with in this article. I hope these explanations are useful for students.
