Wiki je napisal/-a:Sub-disciplines in mechanics

The following are two lists of various subjects that are studied in mechanics.

Note that there is also the "theory of fields" which constitutes a separate discipline in physics, formally treated as distinct from mechanics, whether classical fields or quantum fields. But in actual practice, subjects belonging to mechanics and fields are closely interwoven. Thus, for instance, forces that act on particles are frequently derived from fields (electromagnetic or gravitational), and particles generate fields by acting as sources. In fact, in quantum mechanics, particles themselves are fields, as described theoretically by the wave function.

[edit] Classical mechanics

The following are described as forming Classical mechanics:

* Newtonian mechanics, the original theory of motion (kinematics) and forces (dynamics)
* Hamiltonian mechanics, a theoretical formalism, based on the principle of conservation of energy
* Lagrangian mechanics, another theoretical formalism, based on the principle of the least action
* Celestial mechanics, the motion of heavenly bodies: planets, comets, stars, galaxies, etc.
* Astrodynamics, spacecraft navigation, etc.
* Solid mechanics, elasticity, the properties of (semi-)rigid bodies
* Acoustics, sound ( = density variation propagation) in solids, fluids and gases.
* Statics, semi-rigid bodies in mechanical equilibrium
* Fluid mechanics, the motion of fluids
* Soil mechanics, mechanical behavior of soils
* Continuum mechanics, mechanics of continua (both solid and fluid)
* Hydraulics, mechanical properties of liquids
* Fluid statics, liquids in equilibrium
* Applied mechanics, or Engineering mechanics
* Biomechanics, solids, fluids, etc. in biology
* Biophysics, physical processes in living organisms
* Statistical mechanics, assemblies of particles too large to be described in a deterministic way
* Relativistic or Einsteinian mechanics, universal gravitation

[edit] Quantum mechanics

The following are categorized as being part of Quantum mechanics:

* Particle physics, the motion, structure, and reactions of particles
* Nuclear physics, the motion, structure, and reactions of nuclei
* Condensed matter physics, quantum gases, solids, liquids, etc.
* Quantum statistical mechanics, large assemblies of particles
