kinematics

[kin′əmat′iks, kī-′]
Etymology: Gk, kinema, motion
the description, measurement, and recording of body motion without regard to the forces acting to produce the motion. Recordings of body motions are defined in one-plane relationships, although natural motions of the body often occur in more than one plane. Kinematics considers the motions of all body parts relative to the segments of the part involved in the motion and not necessarily in relation to the standard anatomical position. For example, the movements of the fingers are considered in relation to the midline of the hand, not the midline of the body. The most common types of motions studied in kinematics are flexion, extension, adduction, abduction, internal rotation, and external rotation. Kinematics is especially important in orthopedics, rehabilitation medicine, and physical therapy. Also spelled cinematics. Compare kinetics.

To get insight into the various processes of galaxy mass assembly, the Mass Assembly Survey with SINFONI in VVDS (MASSIV) aims at probing the kinematical and chemical properties of a significant and representative sample of high-red-shift (0.
The basic modules are structural in nature like base, columns, and slide ways and the auxiliary modules are kinematical or motion providing modules such as spindle heads, tool changers, spacers, indexing units, adapter plates and angle structure, etc.
In principle, the Huttlin-Kugelmotor is a 4-stroke engine, which, however, follows a completely new kinematical principle.
Although the values of kinematical viscosity of the analyzed oils differed vastly at a temperature of 50[degrees]C (Wrzecion 2-8 mm2/s, L--AN 22-22 [mm.

The simplest ones consist in modifying the standard approach of Naka-mura (4): the Avrami parameter or the crystallization kinetic function is increased by a multiplying factor which is linked to flow kinematical variables, such as shear intensity (5), shear rate (6), macroscopic strain (7), and molecular orientation (8).
The variables of special relativity, they argue, are kinematical, not physical, though powerful forces in the popular and scientific communities have vested interests in obscuring the fact.
