# Thread: Why do things appear to move faster when they're closer to us?w

1. Why do things that are closer to us appear to move faster than those that are farther away from us?

2.

3. Here's a link (hopefully) explaining it:
Parallax - Wikipedia, the free encyclopedia

4. Because the angle covered (in the visual field) is greater close up than it is far away.
Thus we get the (entirely false) impression that, since it's gone through a larger angle (in a given time), it must be moving faster.

(It's not something I am especially familiar with, but if you don't know the term 'Parallax' then it is not exactly a word you can guess.)

7. A meter stick closer 10 meters from you takes up less field of view than 100 meters away.

Uh yeah.
A metre at 10 metres subtends 100 millirad.

100 is less than 10, right.

That is a bit of a crap super-power: "The further away he is, the slower he moves!"

That's because he is getting tired of running away.

TBH: the further I run away, the slower I get - but that's not a super-power. That's a lack of aerobic training.
