Classical theories in physics usually refer to those theories that have predictability or determinancy. The theories don't embody the uncertainty principle that quantum mechanics has. And so, the only branch I can think of right now is only General Relativity.
they are both under science
The main branches of classical physics include: Classical Mechanics Electromagnetism Classical Optics Thermodynamics Fluid mechanics In modern physics, there are a lot of different fields of study including: The Special Theory of Relativity The General Theory of Relativity Quantum Mechanics. Nuclear Particle Physics Solid state physics, incuding semiconductors. Statistical thermodynamics Quantum Electrodynamics (QED) Quantum Chromodynamics (QCD) In Modern Physics, optics and electricity & magnetism have been unified, especially through the use of Special Relativity. [Three of the most important fields of Modern Physics had been left out. I have put them first , second, and third on the list. By definition, these are Modern Physics because they are products of the 20th century. Also, some very important parts of Classical Physics had been left out, such as fluid mechanics.]

There are three big branches that cover absolutely everything. Life Physical (Physics, basically) Earth Everything else falls under that.
There are 2 subdivisions of physics, classical physics and modern physics. Classical physicals is mainly concerned with matter and energy on the normal scale of observation, while modern physics deals behavior of matter and energy under extreme conditions.
"Modern Physics" is a heading commonly used to introduce the studies of light and Quantum Physics, the Correspondence Principle, the Uncertainly Principle, Waves and Particles, Wave Mechanics and the Schrödinger Probability equation, nuclear physics, and Relativity.
Not quite sure the question, but maybe "Physics" is what you're looking for? Astronomy is often considered an off-shoot of Physics and classes may only be offered through the Physics department if an Astronomy department does not exist.
Mechanics is a branch of science that deals with the behavior of physical bodies under force or displacement.
Modern physics. More specifically, the Theory of Relativity.
The branch included is electronics with a bit programming of Embedded for the microcontroller and processor used thus fully comes under electronics
Traditional physics are more commonly called "Classical Physics" and it was created by the old giants of physicists like Newton and Galileo.Modern physics are the newer study of physics that was created by folk like Einstein and Schrodinger.The main difference is that classical physics deals in things that are relatively and easily handled by human size in terms of observation, forces and speeds. Things like the motion of baseballs, cars and planets.Modern physics deal in things that are small or fast. Time dilation due to traveling near the speed of light falls under modern physics as does the world of subatomic particles. The nature of electromagnetic radiation roughly follows the same wave math involved in classical physics, however, things get deeper when we begin to discuss the wave-particle duality of matter and light so it is more modern physics.
physics pinned with maths, comes under science
