Dynamics
From Wikipedia, the free encyclopedia Jump to: navigation, searchDynamics (from Greek Greek , an independent branch of the Indo-European family of languages, is the language of the Greeks. Native to the southern Balkans, it has the longest documented history of any Indo-European language, spanning 34 centuries of written records. In its ancient form, it is the language of classical ancient Greek literature and the New Testament of δυναμικός - dynamikos "powerful", from δύναμις - dynamis "power") may refer to:

Physics and engineering
- Dynamics (mechanics) In the field of physics, the study of the causes of motion and changes in motion is dynamics. In other words the study of forces and why objects are in motion. Dynamics includes the study of the effect of torques on motion. These are in contrast to Kinematics, the branch of classical mechanics that describes the motion of objects without, the time evolution of physical processes
- Aerodynamics Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is a subfield of fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics, with the difference being that gas dynamics applies to, the study of gases in motion
- Analytical dynamics In classical mechanics, analytical dynamics, or more briefly dynamics, is concerned about the relationship between motion of bodies and its causes, namely the forces acting on the bodies and the properties of the bodies . The foundation of modern day dynamics is Newtonian mechanics and its reformulation as Lagrangian mechanics and Hamiltonian refers to the motion of bodies as induced by external forces
- Flight dynamics Flight dynamics is the science of air and space vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of mass, known as pitch, roll and yaw, the science of aircraft and spacecraft design
- Fluid dynamics In physics, fluid dynamics is a sub-discipline of fluid mechanics that deals with fluid flow—the natural science of fluids in motion. It has several subdisciplines itself, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, or hydrodynamics, the study of fluid flow
- Computational fluid dynamics Computational fluid dynamics is one of the branches of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the millions of calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. Even with high-, a way of studying fluid dynamics using numerical methods
- Molecular dynamics Molecular dynamics is a form of computer simulation in which atoms and molecules are allowed to interact for a period of time by approximations of known physics, giving a view of the motion of the particles. This kind of simulation is frequently used in the study of proteins and biomolecules, as well as in materials science. It is tempting, though, the study of motion on the molecular level
- Langevin dynamics, an approach to the mathematical modeling of molecular dynamics
- Brownian dynamics Brownian dynamics can be used to describe the motion of molecules in molecular simulation. It is a simplified version of Langevin dynamics and corresponds to the limit where no average acceleration takes place during the simulation run. This approximation can also be described as 'overdamped' Langevin dynamics, or as Langevin dynamics without, a simplified version of Langevin dynamics
- Langevin dynamics, an approach to the mathematical modeling of molecular dynamics
- Quantum chromodynamics In theoretical physics, quantum chromodynamics is a theory of the strong interaction (color force), a fundamental force describing the interactions of the quarks and gluons making up hadrons (such as the proton, neutron or pion). It is the study of the SU(3) Yang–Mills theory of color-charged fermions (the quarks). QCD is a quantum field theory, a theory of the strong interaction (color force)
- Quantum electrodynamics Quantum electrodynamics is the relativistic quantum field theory of electrodynamics. QED was developed by a number of physicists, beginning in the late 1920s. It basically describes how light and matter interact. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons, description of how matter and light interact
- Relativistic dynamics Relativistic dynamics refers to a combination of relativistic and quantum concepts to describe the relationships between the motion and properties of a relativistic system and the forces acting on the system. What distinguishes relativistic dynamics from other physical theories is the use of an invariant scalar evolution parameter to monitor the, a combination of relativistic and quantum concepts
- Stellar dynamics Stellar dynamics is the branch of astrophysics which describes in a statistical way the collective motions of stars subject to their mutual gravity. The long range of gravity and the slow "relaxation" of stellar systems prevent the use of the methods of statistical physics. The motion of stars in a galaxy or in a globular cluster are, in astrophysics, a description of the collective motion of stars
- System dynamics System dynamics is an approach to understanding the behaviour of complex systems over time. It deals with internal feedback loops and time delays that affect the behaviour of the entire system. What makes using system dynamics different from other approaches to studying complex systems is the use of feedback loops and stocks and flows. These, the study of the behavior of complex systems
- Thermodynamics In science, thermodynamics is the study of energy conversion between heat and mechanical work, and subsequently the macroscopic variables such as temperature, volume and pressure, the study of the relationships between heat and mechanical energy
Sociology and psychology
- Group dynamics Group dynamics is the study of groups, and also a general term for group processes. Relevant to the fields of psychology, sociology, and communication studies, a group is two or more individuals who are connected to each other by social relationships. Because they interact and influence each other, groups develop a number of dynamic processes that, the study of social group processes
- Power dynamics, the dynamics of power Power is a measure of an entity's ability to control the environment around itself, including the behavior of other entities. The term authority is often used for power, perceived as legitimate by the social structure. Power can be seen as evil or unjust, but the exercise of power is accepted as endemic to humans as social beings. Often, the study, used in sociology
- Psychodynamics The original concept of "psychodynamics" was developed by Sigmund Freud. Freud suggested that psychological processes are flows of psychological energy in a complex brain, establishing "psychodynamics" on the basis of psychological energy, which he referred to as libido, the study of the underlying psychological forces driving human behaviour
- Spiral Dynamics Spiral Dynamics is a theory of human development introduced in the 1996 book Spiral Dynamics by Don Beck and Chris Cowan. The book was based on the theory of psychology professor Clare W. Graves, and originally targeted at a business management audience. "Spiral Dynamics" is a registered trademark of the National Values Center, Inc, a social development theory
- Social dynamics Social dynamics is the study of the ability of a society to react to inner and outer changes and deal with its regulation mechanisms. Social dynamics is a mathematically inspired approach to analyse societies, building upon systems theory and sociology. Sociologists, ethnologists, economists, social psychologists, criminologists, anthropologists, the ability of a society to react to changes
Computer science and mathematics
- Dynamical system The dynamical system concept is a mathematical formalization for any fixed "rule" which describes the time dependence of a point's position in its ambient space. Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each spring in a lake, a concept describing a point's time dependency
- Symbolic dynamics, a method to model dynamical systems
- Dynamic programming In mathematics and computer science, dynamic programming is a method of solving complex problems by breaking them down into simpler steps. It is applicable to problems that exhibit the properties of overlapping subproblems which are only slightly smaller and optimal substructure . When applicable, the method takes much less time than naive methods, a method of solving complex problems by breaking them down into simpler steps
- Dynamic program analysis, a set of methods for analyzing computer software

The company has changed markedly in the post-Cold War era of defense consolidation. The company has four main business segments: Marine Systems, Combat Systems, Information Systems, defence contractor
Other
- Dynamics (music) In music, dynamics normally refers to the volume of a sound or note, but can also refer to every aspect of the execution of a given piece, either stylistic or functional (velocity). The term is also applied to the written or printed musical notation used to indicate dynamics. Dynamics do not indicate specific volume levels, but are meant to be, the softness or loudness of a sound or note
- Force Dynamics Force Dynamics is a semantic category that describes the way in which entities interact with reference to force. Force Dynamics gained a good deal of attention in cognitive linguistics due to its claims of psychological plausibility and the elegance with which it generalizes ideas not usually considered in the same context. The semantic category, a semantic concept about how entities interact with reference to force
- Microsoft Dynamics Microsoft Dynamics is a line of ERP and CRM (customer relationship management) applications developed by the Microsoft Business Solutions group within Microsoft. Microsoft Dynamics applications are delivered through a network of reselling partners who provide specialized services. There are 300,000 businesses that use Microsoft Dynamics, a line of business software
- Neural oscillation Neural oscillation is rhythmic or repetitive neural activity in the central nervous system. Neural tissue can generate oscillatory activity in many ways, driven either by mechanisms localized within individual neurons or by feedback interactions among populations of neurons. In individual neurons, oscillations can appear either as subthreshold in the field of neurodynamics, a rhythmic pattern in the brain
- Population dynamics Population dynamics is the branch of life sciences that studies short- and long-term changes in the size and age composition of populations, and the biological and environmental processes influencing those changes. Population dynamics deals with the way populations are affected by birth and death rates, and by immigration and emigration, and, in life sciences, the changes in the composition of a population
