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.]
they are both under science
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.
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.
"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.
Biology, the study of animal and plant life. Chemistry, the study of chemicals and medicine. Physics, the study of the laws of physics, magnetics, electricity, and other things affecting the Earth. There are other uncommon branches of Science, but they all fall under these three categories. The actual answer is that the three main divisions of science are Physical Science's, Biological or Life Science's and Social Science's.

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.
Examples of classical physics include Newton's laws of motion, the principles of classical mechanics, and the study of electromagnetism by Maxwell's equations. These concepts describe the motion of objects under the influence of forces and the behavior of charged particles in electric and magnetic fields.

Classical physics refers to the branch of Physics whereby energy and matter are two very different concepts. It is usually based on the theory of electromagnetic radiation and the laws of motion.
Forces are introduced in Newtonian mechanics and are a fundamental idea of classical physics. In classical physics, that is the physics that describes human dimension phenomena (like the motion of a car, the flowing of water in ducts, the gravitational attraction on the earth surface and so on) , the study of force laws is one of the key elements and this is an important point also in biophysics, macroscopic chemistry and several other science branches based on classical mechanics. Energy was originally introduced in classical physics too, but only the quantum and relativistic physics have clarified completely its deep meaning so that in modern physics energy has substituted the concept of force as the key physical quantity in the study of physical systems evolution. Naturally, chemistry at atomic level, astrophysics and so on share completely this characteristics.
There are three big branches that cover absolutely everything. Life Physical (Physics, basically) Earth Everything else falls under that.
"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.
