If this did not happen, there would be no such thing as vibration.">> 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. :-) Jim Bryant (FL)
