Uhh JD...the definition of "vibration as relates to physics is:

vibration (n)
...........
"2. Physics. a. A rapid linear motion of a particle or of an elastic solid 
about an equilibrium position. b. A periodic process.
3. A single complete vibrating motion; a quiver." AHD

and for "velocity it is:
velocity (n)
..........
2. Abbr. V. Physics: A vector quantity whose magnitude is a body's speed and 
whose direction is the body's direction of motion. AHD

 This seems to dispute your comment(s) or have 
I missed something along the way. :-)
