Imagine a tool that would establish the position of a moving object at constant intervals of your time - for instance, each second or every 1/10-th second or maybe every 1/60-th second. maybe such a device could track the situation of a object occupation 1-dimension by inserting a dot on a strip of paper. The path of dots would represent the motion of the article because it changes its position over the course of time.
Believe it or not, there's such a device - it' referred to as a ticker tape timer. Before the arrival of computers in Physics labs, a typical means of analyzing the motion of objects in physics labs was to perform a ticker tape analysis. an extended tape was hooked up to a moving object and rib through a tool that placed a tick upon the tape at regular intervals of your time - say each 0.10 second. because the object moved, it dragged the tape through the "ticker," thus going away a path of dots. The trail of dots provided a history of the object' motion and so a illustration of the object' motion.

Dot Diagram
While the employment of ticker tape associate aliases in Physics labs has largely been replaced by the use of computer-interfaced motion detectors, the use of ticker tapes or motion diagrams still persists in our Physics program thanks to the visual nature of representing an object' motion. Such diagrams are cited as dot diagrams, motion diagrams, oil drop diagrams, and (still) ticker tape diagrams.
the space between dots on a dot diagram represents the article' position amendment throughout that point interval. an outsized distance between dots indicates that the object was moving quick during that time interval. A small distance between dots suggests that the article was moving slow throughout that point interval. Dot diagrams for a fast- and slow object are pictured below.

The associate aliases of a dot diagram will reveal if the thing is moving with a relentless speed or accelerating. A dynamic distance between dots indicates a changing velocity and thus an acceleration. a relentless distance between dots represents a constant velocity and thus no acceleration. Dot diagrams for objects moving with a constant velocity and with an accelerated motion are shown below.

And so dot diagrams give a new suggests that of representing numerous options of the motion of objects.
