Ans:
Due to the vast scope and research in physics, it is usually divided into several branches some of them given below:
Mechanics:
Description: Motion of objects and how it relates to forces.
Examples: falling objects, friction, weight, spinning objects
Heat and Thermodynamics:
Description: Heat and temperature their related to energy.
Examples: melting and freezing processes, engines, refrigerators
Oscillations and Waves:
Description: to and fro motion.
Examples: Springs, Water waves, Sound
Optics:
Description: Light and the instrument created to use or detect it.
Examples: Mirrors, Lenses, telescopes, Eye
Electricity and Magnetism:
Description: Static as well as moving charges and associated physical phenomena.
Examples: electrical charge, circuitry, magnets, electromagnets
Atomic and Nuclear:
Description: Structure and properties of individual atoms and nuclei of an atom.
Examples: X-rays, LASERS, Nuclear Reactor, MRI, CT Scan, PET Scan
Relativity:
Description: Moving objects (including very high speed) and gravitation.
Examples: Particle accelerators, Nuclear Energy
Quantum Physics:
Description: Discrete, indivisible units of energy called quanta.
Examples: the atom and its parts
Particle Physics:
Description: The nature of the particles that matter and radiation.
Examples: Quarks, Leptons, Photons, Bosons
Cosmology and astrophysics:
Description: the origin, evolution, and eventual fate of the universe.
Examples: Stars, galaxies and black holes
Biophysics and Medical Physics:
Description: physical interactions of biological processes and Application of physics health processes such as prevention, diagnosis and treatment.
Examples: MRI, CT Scan, Radiotracers, and conduction in living cells.
