Mainly:
Mechanics (Newtonian & relativistic): - mater - time - space;
Molecular physics & thermodynamics: - physics of thermal movement;
Electromagnetism: - physics of E,H - field;
Wave motion: - physics of sound, light, ..., solitons (tsunami);
Quantum physics: physics of micro-world;
High energy physics.
The two major divisions in physics are classical and modern physics. The subdivisions on the other hand are mechanics, thermodynamics, acoustics and so many more.
There are many different subdivisions of classical physics. These subdivisions can be categorized as dynamics, hydrodynamic, acoustics, optics, mechanics, statics, magnetism, thermodynamics, and electricity. Basically, classical physics is physics dealing with things we can see or touch.
The subdivisions of modern physics include quantum mechanics, relativity theory, particle physics, condensed matter physics, and astrophysics/cosmology. Each of these areas focuses on different aspects of the physical world, from the behavior of subatomic particles to the structure of the universe itself.
You could do worse than consider the 15 science divisions at the head of the SCIENCE subdivision in this answers.com. That will give you a good start. You'll find that several of the primary divisions in science have, in turn, subdivisions below them.

There are three subdivisions: Lyric, Drama, and Epic.
Psilotum is divided into two main subdivisions: Psilotum and Tmesipteris. These subdivisions are based on differences in sporangial structure and plant morphology.
What sort of proof do you want? It has certainly been found that modern physics (on the one hand, quantum physics, on the other hand, the theory of relativity) provides a more precise description of the Universe than classical physics.
Kinematics is the study of motion within physics, if that's what you're getting at.
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.
The branch of physics referred to as mechanics.
The two subdivisions of the Precambrian Era are the Hadean and the Archean Eons.
