What's the difference between motion and reptation?
Motion
Definition:
(n.) The act, process, or state of changing place or position; movement; the passing of a body from one place or position to another, whether voluntary or involuntary; -- opposed to rest.
(n.) Power of, or capacity for, motion.

(n.) Change in the relative position of the parts of anything; action of a machine with respect to the relative movement of its parts.
(n.) Movement of the mind, desires, or passions; mental act, or impulse to any action; internal activity.
(n.) A proposal or suggestion looking to action or progress; esp., a formal proposal made in a deliberative assembly; as, a motion to adjourn.

(n.) Change of pitch in successive sounds, whether in the same part or in groups of parts.
(n.) A puppet show or puppet.
(v. i.) To make a significant movement or gesture, as with the hand; as, to motion to one to take a seat.

Reptation
Definition:
(n.) The act of creeping.
Example Sentences:
(1) Using fundamental concepts of hydrodynamics in porous media, we have rederived the Lumpkin-DèJardin-Zimm (LDZ) model for the gel electrophoresis of reptating, infinitely long, worm-like chains, such as DNA.

(6) The dependence of effective radius on PE and the proximity of 2.PcE to the length of the rod are explained by (a) random orientation of rods at PE values in the region of the plateau, and (b) increasingly preferential end-first orientation (reptation) of the rod as PE decreases below PcE.
(7) The other process, slow, is characterized by a reptation time and a mean orientation factor in good agreement with the biased reptation model without overstretching.
