What are the Branches of Physics?

Physics is divided into several core branches, each focusing on a specific area of the physical world. Here are the 7 major branches of Physics you should know:

1. Thermodynamics- Focuses on the study of heat, temperature, and energy transfer. It explains how energy moves between systems and how it affects matter.
2. Mechanics- Deals with motion, forces, and the behavior of physical objects. It includes concepts like velocity, acceleration, and Newton’s laws of motion.
3. Relativity- Studies objects moving at very high speeds and how time, space, and gravity behave differently at those speeds. It’s best known through Einstein’s theories of Special and General Relativity.
4. Electromagnetism- Explores electricity, magnetism, and light. It includes topics like electric circuits, magnetic fields, electromagnetic waves, and how they interact.
5. Optics- Involves the study of light and how it behaves when it interacts with mirrors, lenses, and different materials, producing phenomena like reflection, refraction, and color dispersion.
6. Quantum Mechanics- Focuses on the behavior of matter and energy at atomic and subatomic levels. It explains phenomena that classical physics cannot, such as the behavior of electrons and photons.
7. Vibrations and Wave Phenomena- Covers repetitive motions and wave behavior, including sound, musical instruments, and even seismic activity.
