Answer:

While the use of ticker tape analyses in Physics labs has mostly been replaced by the use of computer-interfaced motion detectors, the use of ticker tapes or motion diagrams still persists in our Physics curriculum due to the visual nature of representing an object's motion. Such diagrams are referred to as dot diagrams, motion diagrams, oil drop diagrams, and (still) ticker tape diagrams.

The distance between dots on a dot diagram represents the object's position change during that time interval. A large distance between dots indicates that the object was moving fast during that time interval. A small distance between dots means the object was moving slow during that time interval. Dot diagrams for a fast- and slow-moving object are depicted below.
