The main branches of physics include classical mechanics, electromagnetism, thermodynamics, relativity, and quantum mechanics.
Theoretical physics deals with developing and testing theories to explain the laws and principles of the physical world, while experimental physics involves conducting experiments to test these theories and gather data.
Applied physics is the application of principles and theories of physics to solve real-world problems. Examples include engineering, materials science, medical physics, and geophysics.
Astrophysics focuses on the study of celestial objects and phenomena in the universe, such as stars, galaxies, and black holes. It combines principles from other branches of physics, such as electromagnetism and thermodynamics, to understand the behavior of these objects.
Mathematics is a fundamental tool in physics, used to describe and quantify physical phenomena and relationships between them. It allows physicists to make precise predictions and create mathematical models to understand the underlying principles of the physical world.
