Discussion Overview

The discussion revolves around the phenomenon of air movement generated by hand motion, specifically exploring the conditions under which moving a hand creates a noticeable airflow or "wind." Participants examine the relationship between the speed and distance of hand movement and the resulting air displacement.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants note that moving a hand faster over a longer distance results in more air being displaced, while shorter distances yield less air movement.
  • One participant suggests that the volume of air moved is smaller when the distance is shorter, implying a relationship between distance and air displacement.
  • Another participant expresses surprise at the observed phenomenon and seeks further explanation regarding the mechanics involved.
  • A participant questions whether the air movement created by hand motion can be classified as "wind" or if it is merely a disturbance of existing air.
  • A mentor mentions that air can indeed be moved, but the terminology used to describe it may not be a physics issue.

Areas of Agreement / Disagreement

Participants generally agree that hand motion can move air, but there is no consensus on the terminology used to describe this movement or the underlying mechanics of why distance affects air displacement.

Contextual Notes

The discussion does not resolve the assumptions regarding the definitions of "wind" and the mechanics of air movement, leaving these points open for further exploration.

Why when I move my hand faster to long distance and apply force I get more air but when I move my hand fast to shorter distance I barely get any air

The shorter the distance, the less air you move, because the volume passed by the hand is smaller.

And this is surprising, why exactly?

Maybe @Ghostinthemachine you could describe what you think should happen.
 
can we make wind during motion for example when I move my hands or it’s just wind disturbance and wind that is already there?

You can move air. Whether to call that ”wind” or not isn’t a physics question.
