Partical motion is the answer
An ocean buoy bobs up and down as a wave passes by because the wave causes the water particles to move in circular orbits. The buoy reacts to these circular motions by moving up and down as the wave passes underneath it.
The word buoy can be a noun or a verb.noun -- The buoy marks the entrance to the channel.verb -- The life jacket buoyed him up. - past tense..
The buoy moves up and down as the water passes beneath it.
When a water wave passes a buoy, the buoy will move up and down in response to the wave passing underneath it. This motion is known as heaving, and the buoy will follow the shape of the passing wave, moving with the oscillations of the water particles. The buoy will return to its original position once the wave has passed.
When a water wave passes, a buoy moves up and down with the wave motion, but it does not move forward with the wave. The buoy remains in the same location and oscillates in response to the passing wave, but it does not travel along with the wave.
Buoys have been designed to operate using the motion of waves to dirve a generator within the buoy. The up and down action causes a plunger to move within an armature and thus producing current
A cable buoy is an empty cask employed to buoy up a cable in rocky anchorage.

Poor Bob doesn't do much strumming these days but when he was alive he was a down, down up down up up kinda guy. Sorry, I just couldn't help myself.
