It would be interesting to do the math to see what influence gravity due to the fan blades mass would have on the downward trajectory of a dust particle. I would think Earth's gravity would be dominant, and a particle would be deflected minutely.
I am much more concept orientated than math. Distance I am sure will come into play with regard to mass and attraction as when a force is more dominate regarding vector angles. Again, I am more conceptual. Kinda like the movie 'Armageddon' Thanks! :)
What a great answer! I leave my fans on all the time, and of course the kitchen fan gets dirtier than the others. I tried apply paste wax to them, but it didn't help.
For any nerds out there interested in such trivia, I just did the math. It turns out that a 50 kg mass at 10 cm distance would accelerate a 1 microgram piece of dust to walking speed in 7 weeks! (Using F=Gm1m2/r^2)
LOL, LOL, LOL The solution set is Fantastic and paper towels :)
Great work! As said I just ponder. However I enjoy fun. http://www.spaceflight.esa.int/impress/text/educat... or Impress Education (ESA): Circular Motion where the formulas for mass of rotating objects are shared. Again, I don't understand this stuff
