# Dynamics

(Redirected from Dynamics (disambiguation))

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
• 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

## Computer science and mathematics

• Dynamic data structure, a structure where the data elements may change
• Dynamical system, a concept describing a point's time dependency
• Dynamic programming, a method of solving complex problems by breaking them down into simpler steps
• Dynamic program analysis, a set of methods for analyzing computer software
• Dynamic HTML, an umbrella term for a collection of technologies used together to create interactive and animated web sites
• Dynamic web page, a web page with web content that varies based on parameters provided by a user or a computer program
