  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]

From The Collaborative International Dictionary of English v.0.48 :

  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]

From WordNet (r) 3.0 (2006) :

  dynamics
      n 1: the branch of mechanics concerned with the forces that
           cause motions of bodies [syn: dynamics, kinetics]
