Parallax is the apparent shift in the position of an object when viewed from different angles. This effect is most noticeable for objects that are relatively close to the observer.
Here's how it works:
* Imagine you're holding your finger out in front of your face.
* Close one eye and then the other.
* Notice how your finger seems to jump back and forth against the background.
This is because the angle from which you are viewing your finger changes slightly when you switch eyes. The same principle applies to moving objects, although the change in angle is usually caused by the object's movement and not the observer's.
Important Note: While parallax is a common phenomenon, it's important to distinguish it from the actual curved motion of objects. Parallax only refers to the *apparent* curvature, not the real one.
