Similarly, you can also see distant objects while traveling by plane. like it’s going too slow you can feel it. Average passenger aircraft at an altitude of 8,500-10,500 meters and with a speed of 900-1020 km/h may seem slow to you.

The reason for this situation is complete it’s about the way our perception works. It even has a name in literature.

We perceive nearby objects as “faster”.

For example, while driving the car, the trees along the road (nearby object) are fast, distant objects such as the sun or moon We see it as moving slowly.

While a passenger jet actually moves quite fast as shown in this video.

The name of this condition in the literature is “motion parallax”. your field of vision see it as a frame, Objects moving at a constant speed across this frame are perceived as moving faster when closer than when further away.

This is called “motion parallax”. This phenomenon the moving object it is valid in relation to the observer (us looking at the plane while traveling in a car) acting in relation to himself or in relation to the object.

The percentage of our field of view also causes us to perceive the distance the object moves differently.

The effect is due to the distance the object travels compared to the percentage of our field of view. For example, in the above image, an object 100 meters away can move 20 meters in a given direction and field of view only moves about 25% of the time.

However, a displacement of 20 meters on an object only 40 meters away, the object is completely out of sight. causes.

In short, thanks to motion parallax, we perceive a distant plane as slower.

So we observe that objects close to us move faster than distant objects. To determine this distance visual cues basic and motion parallax is formed.
