# Class 12 Physics Chapters

A foundation stone for fields in science, Physics is a branch of science dealing with studying the structure of matter and how the fundamental components of the universe interact. The subject studies the aspects ranging from small objects using quantum mechanics to the entire universe. The physics taught in senior secondary level makes the foundation for competitive exams like NEET and other medical exams. Besides, it is an inseparable component of Engineering courses. Class 12 Physics covers a majority of topics that are required to clear the basics about the subject. To get an overview of the syllabus and everything that is covered in it, read our comprehensive blog on Physics syllabus for class 12th. If you want to read the content covered in the class 12 Physics chapters, keep reading the blog.
