Every object experiences some form of motion which is the result of different forces acting on the object. Dynamics is the study of the forces which are responsible for this motion. Dynamics (from Greek δυναμικός ''dynamikos'' "powerful", from δύναμις ''dynamis'' "power") may refer to: ==Physics and engineering== * Dynamics (mechanics), * * Aerodynamics, the study of gases in motion * * Analytical dynamics, the motion of bodies as induced by external forces * * Anomalous dynamics (Random walk#Anomalous diffusion), the stochastic motion of objects with mean squared displacement (''MSD'') that deviates from the relation for normal dynamics, ''MSD''~''t'', where ''t'' is the time the process is seen; anomalous dynamics are either faster than normal dynamics (''MSD''>''t'') or slower (''MSD''<''t'') * * Astrodynamics, also known as Orbital mechanics for both near earth and planetary motion (also called Celestial mechanics when used in that sense). * * Brownian dynamics, the occurrence of Langevin dynamics in the motion of particles in solution (e.g. a grain in water, as was first seen by Brown); its famous property is: ''MSD''~''t'', where ''MSD'' is the mean squared displacement, and ''t'' is the time the process is seen * * File dynamics, stochastic motion of particles in a channel * * Flight dynamics, the science of aircraft and spacecraft design * * Fluid dynamics or ''hydrodynamics'', the study of fluid flow * * * Computational fluid dynamics, a way of studying fluid dynamics using numerical methods * * Fractional dynamics, studies the dynamics with integrations and differentiations of fractional orders (in physics, economics, and related fields) * * Molecular dynamics, the study of motion on the molecular level * * Normal dynamics, is a stochastic motion having a Gaussian probability density function in position with variance ''MSD'' that follows, ''MSD''~''t'', where ''MSD'' is the mean squared displacement of the process, and ''t'' is the time the process is seen (normal dynamics and Brownian dynamics are very similar; the term used depends on the field) * * Langevin dynamics, a mathematical model for stochastic dynamics; used in modeling molecules, yet also the stock market and other systems * * Quantum chromodynamics, a theory of the strong interaction (color force) * * Quantum electrodynamics, a description of how matter and light interact * * Relativistic dynamics, a combination of relativistic and quantum concepts * * Single file dynamics (also termed file dynamics), the diffusion of particles in a channel * * Stellar dynamics, a description of the collective motion of stars * * System dynamics, the study of the behavior of complex systems * * Thermodynamics, the study of the relationships between heat and mechanical energy 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dynamics」の詳細全文を読む スポンサード リンク
