Classical Mechanics and Wave Theory.
Quantum Mechanics "replaced" Classical Mechanics in particle physics in mid-1930s.
The two main branches are : 1) Classical Mechanics 2) Quantum Mechanics
Physics Branches: Classical Mechanics Mathematical Physics Classical Electrodynamics Quantum Mechanics Thermodynamics and Statistical Mechanics Condensed Matter Physics Nuclear Physics Quantum Field theory Non-Linear Dynamics Astronomy and Astrophysics General Theory of Relativity and Cosmology
the classification of mechanics are:- # Classical Mechanics # Statistical Mechanics # Quantum Mechanics
Physics Branches: Classical Mechanics Mathematical Physics Classical Electrodynamics Quantum Mechanics Thermodynamics and Statistical Mechanics Condensed Matter Physics Nuclear Physics Quantum Field theory Non-Linear Dynamics Astronomy and Astrophysics General Theory of Relativity and Cosmology
There are six divisions of physics. There are classical mechanics, thermodynamics and statistical mechanics, electromagnetism, relativity, quantum mechanics, and interdisciplinary fields.
They both have protons and electrons.And both the theories agree to the supposition that electrons revolve around the nucleus of the atom. They both state that higher energy electrons are located further from the nucleus.apex approved!!
"Classical mechanics" is what you get when you have large groups of particles. Large objects do obey the laws of quantum mechanics, but things such as the "uncertainty of momentum" become quite insignificant at larger scales.With individual particles, seen or otherwise - the laws of the quantum world become more relevant.
In the microworld the study of motion is called mechanics or classical mechanics. The study of the motion of particles in the microworld of atoms and nuclei is called quantum mechanics.

Classical physics is the physics without considering quantum mechanics. This is the type of physics practiced by for example Newton (you might also come across the term Newtonian physics). General relativity is also a classical theory. The distinction is often used because quantum mechanics changed quite a bit in many fields of physics, so the term 'classical physics' allows for a clear distinction. The opposite of classical physics would be quantum physics.
