Why does an animated image appear to move? A. Humans interpret quickly-changing still images as being in motion B. Humans interpret a single static image as if it were moving C. The eye moves across the image D. The image scrolls very slowly

Answer 1

The correct answer is A. Humans interpret quickly-changing still images as being in motion. This phenomenon is known as "persistence of vision," where our brains perceive a series of slightly different images in rapid succession as smooth motion. This principle is the basis for animations and film, where a sequence of images is presented at a rate (typically 24 frames per second or more) that makes them appear to move.
