Dynamics - Physics and Engineering

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)
  • 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
