> Doesn’t movement generate heat?
If you’re an SR71, Concorde or similar, very supersonic aircraft, then yes. For the wind speeds you encounter in everyday situations, increased heat transfer and evaporative cooling far exceed the very slight heating effect of moving air. Even in still air, the average gas molecule is moving at close to 1000 mph, so a few extra mph doesn’t make a significant difference. You don’t feel the effects of the high speed molecules because they’re so tiny and they’re all moving randomly in different directions, cancelling each other out. Combined together they create air pressure.
