Definition of 'dynamics'

(from WordNet)
noun
The branch of mechanics concerned with the forces that cause motions of bodies [syn: dynamics, kinetics]

Definition of 'Dynamics'

From: GCIDE
  • Dynamics \Dy*nam"ics\, n.
  • 1. That branch of mechanics which treats of the motion of bodies (Kinematics) and the action of forces in producing or changing their motion (kinetics). Dynamics is held by some recent writers to include statics and not kinematics. [1913 Webster]
  • 2. The moving moral, as well as physical, forces of any kind, or the laws which relate to them. [1913 Webster]
  • 3. (Mus.) That department of musical science which relates to, or treats of, the power of tones. [1913 Webster]

Definition of 'dynamics'

From: GCIDE
  • Mechanics \Me*chan"ics\, n. [Cf. F. m['e]canique.] That science, or branch of applied mathematics, which treats of the action of forces on bodies. [1913 Webster]
  • Note: That part of mechanics which considers the action of forces in producing rest or equilibrium is called statics; that which relates to such action in producing motion is called dynamics. The term mechanics includes the action of forces on all bodies, whether solid, liquid, or gaseous. It is sometimes, however, and formerly was often, used distinctively of solid bodies only: The mechanics of liquid bodies is called also hydrostatics, or hydrodynamics, according as the laws of rest or of motion are considered. The mechanics of gaseous bodies is called also pneumatics. The mechanics of fluids in motion, with special reference to the methods of obtaining from them useful results, constitutes hydraulics. [1913 Webster]
  • Animal mechanics (Physiol.), that portion of physiology which has for its object the investigation of the laws of equilibrium and motion in the animal body. The most important mechanical principle is that of the lever, the bones forming the arms of the levers, the contractile muscles the power, the joints the fulcra or points of support, while the weight of the body or of the individual limbs constitutes the weight or resistance.
  • Applied mechanics, the principles of abstract mechanics applied to human art; also, the practical application of the laws of matter and motion to the construction of machines and structures of all kinds.
  • orbital mechanics, the principles governing the motion of bodies in orbit around other bodies under gravitational influence, such as artificial Earth satellites. [1913 Webster +PJC]
