Simple. First, let me ask you this. If you're on a planet with no air to cause friction, then what's to stop the flag from waving after you move it?
Wikipedia says:
"5. The flag placed on the surface by the astronauts flapped despite there being no wind on the Moon [69]. Sibrel said "The wind was probably caused by intense air-conditioning used to cool the astronauts in their lightened, un-circulated space suits. The cooling systems in the backpacks would have been removed to lighten the load not designed for Earth’s six times heavier gravity, otherwise they might have fallen over".
* The astronauts were moving the flag into position, causing motion. Since there is no air on the Moon to provide friction, these movements caused a long-lasting undulating movement seen in the flag. There was a rod extending from the top of the flagpole to hold the flag out for proper display (visible under the fabric in many photographs). The fabric's rippled appearance was due to its having been folded during flight and gave it an appearance which could be mistaken for motion in a still photograph. The top supporting rod of the flag was telescopic and the crew of Apollo 11 found they could not fully extend it. Later crews did not fully extend this rod because they liked how it made the flag appear. A viewing of the videotape made during the Moonwalk shows that shortly after the astronauts remove their hands from the flag/flagpole, it stops moving and remains motionless. At one point the flag is in view for well over thirty minutes and it remains completely motionless throughout that period (and all similar periods). (See inertia.) See the photographs below."
