Mechanics

Mechanics is the branch of physics which studies massive bodies that are influenced by mass-based forces and moved.

The discipline has its roots in ancient Greece where Aristotle studied the way bodies behaved when they were thrown through the air (e.g. a stone). However it was Galileo, Kepler and especially Isaac Newton who laid the foundation for much of the so called Newtonian mechanics we know today.

Mechanics is the original discipline of physics, dealing with the macroscopic world. Mechanics encompasses the movement of all matter possessing mass in the universe under the four forces: gravity, the strong and weak interactions, and the electromagnetic interaction.

Some aspects of classical mechanics

 * Acoustics, sound in solids, fluids, etc.
 * Applied / Engineering mechanics
 * Astrodynamics, spacecraft navigation, etc.
 * Hydraulics, fluids in equilibrium
 * Relativistic or Einsteinian mechanics, universal gravitation
 * Solid mechanics, elasticity, the properties of (semi-)rigid bodies
 * Statistical mechanics, large assemblies of particles

Quantum mechanics
The following are categorized as being part of Quantum mechanics:
 * Condensed matter physics, quantum gases, solids, liquids, etc.
 * Nuclear physics, the motion, structure, and reactions of nuclei
 * Particle physics, the motion, structure, and reactions of particles
 * Quantum statistical mechanics, large assemblies of particles
