Perception of far object that is in motion

Click For Summary

Discussion Overview

The discussion focuses on the perception of distant moving objects and why they appear to move more slowly compared to closer objects. It explores concepts related to visual perception, including angles of movement and the effects of distance on size perception.

Discussion Character

  • Conceptual clarification, Exploratory

Main Points Raised

  • One participant suggests that distant objects appear to move slowly because they do not change their position as much in the observer's field of view compared to closer objects.
  • Another participant notes that distant objects also appear smaller, which may relate to their perceived motion.
  • A different participant introduces the concept of 'parallax' as a method used by astronomers to measure distances to nearby stars, implying its relevance to the discussion of perception.
  • One participant expresses gratitude for the information and acknowledges finding the term for the phenomenon helpful.

Areas of Agreement / Disagreement

Participants appear to agree on the basic principles of perception related to distance and motion, but the discussion does not resolve the nuances of these perceptions or their implications.

Contextual Notes

The discussion does not address potential limitations in the assumptions about visual perception or the specific conditions under which these observations hold true.

Why do objects that are distant and moving appear to be moving slowly than the objects that are close?

By this I assume you mean why they do not move as much in your field of view. The reason is that in order to change by the same angle in your field of view, an object which is further away must move further.
 
For the same reason that distant objects appear smaller.
 
Google 'parallax'! This is one of the most accurate ways that astronomers measure distances to (nearby) stars.
 
ty for the info, very useful ... haven't found the word for the phenomena before...^^^** ty
