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:
- Thermodynamics- Focuses on the study of heat, temperature, and energy transfer. It explains how energy moves between systems and how it affects matter.
- Mechanics- Deals with motion, forces, and the behavior of physical objects. It includes concepts like velocity, acceleration, and Newton’s laws of motion.
- 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.
- Electromagnetism- Explores electricity, magnetism, and light. It includes topics like electric circuits, magnetic fields, electromagnetic waves, and how they interact.
- 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.
- 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.
- Vibrations and Wave Phenomena- Covers repetitive motions and wave behavior, including sound, musical instruments, and even seismic activity.
