Perception of far object that is in motion

AI Thread Summary
Distant moving objects appear to move more slowly than nearby objects due to the angle they subtend in the observer's field of view; further objects must travel a greater distance to create the same angular change. This phenomenon is related to the concept of parallax, which is also used by astronomers to measure distances to nearby stars. The perception of size contributes to this effect, as distant objects appear smaller. Understanding this principle clarifies why motion perception varies with distance. This discussion highlights the importance of perspective in visual perception.

Why do objects that are distant and moving appear to be moving slowly than the objects that are close?
 
Physics news on Phys.org
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
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
