At what time(s) do the rockets have the same velocity? Two toy rockets are traveling in the same direction (taken to be the x axis). A diagram is shown of a time-exposure image where a stroboscope has illuminated the rockets at the uniform time intervals indicated.

In physics, they are sharply defined concepts that are not at all synonymous. Distinguishing clearly between them is a prerequisite to understanding motion. Moreover, an easy way to study motion is to draw a motion diagram, in which the position of the object in motion is sketched at several equally spaced instants of time, and these sketches (or snapshots) are combined into one single picture.
