  1. Mechanics :- In mechanics we deals with motion related things or problems.
  2. Thermodynamics:- In thermodynamics we deals with heat related things or problems.
  3. Electrodynamics:- In electrodynamics we deals with Electricity and magnetism.
  4. optics:- In optics we deals with light.
Modern physics

  • The theories of physics which develops approx from 1900 is known as modern physics.
  • the sub branches of modern physics is:-
  1. Atomic physics : In atomic physics we deals with atoms , molecules and its structure.
  2. Nuclear physics : In nuclear physics we deals with properties of nucleas of atoms.
  3. Quantum Physics : In Quantum physics we deals with wave particle duality.
  4. theory of relativity ; In theory of relativity we deals with the very high speed that is speed of light.
