Q2. List with brief descriptions of different branches of physics.

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.
