Can wind/air that is moving at average speeds be slowed down by the cause of Friction? Also, Can Air bubbles in water be slowed down because of Friction? Please cite your sources.

  • $\begingroup$ Just out of curiosity, i do see the relevance in your last statement, but are you suggesting a connection of bubbles in liquids and the formation of the solar system? $\endgroup$ – AtmosphericPrisonEscape Feb 26 at 17:54
  • $\begingroup$ @AtmosphericPrisonEscape I added the relevance statement at the end. It wasn't part of the original question. $\endgroup$ – Connor Garcia Feb 26 at 18:50

    $\begingroup$ @ConnorGarcia: Your interpretation of OP's question then seems quite far-fetched. OP does not indicate this is a question about anything related to the solar system. $\endgroup$ – AtmosphericPrisonEscape Feb 26 at 18:54

    $\begingroup$ @AtmosphericPrisonEscape Yes, probably better off as a comment: This is relevant to astronomy since gas friction is part of the model for the formation of our Solar System. $\endgroup$ – Connor Garcia Feb 27 at 0:13

    $\begingroup$ I’m voting to close this question because it's not a question about astronomy but rather about very basic physics. $\endgroup$ – Chappo Hasn't Forgotten Monica Feb 27 at 2:07

Yes, air and gas are slowed down by friction since they have a non-zero viscosity. From wikipedia:

Viscosity can be conceptualized as quantifying the internal frictional force that arises between adjacent layers of fluid that are in relative motion.

Yes, air bubbles in water are slowed down by friction since water has a non-zero viscosity. Check out this youtube experiment showing bubble rise rates between fluids with various viscosities.
