I used one back in the dim, dark, recesses of the past. A strip of
lightweight paper could be drawn through the device and the spark would
puncture the paper at even time intervals. The paper is then attached to
the mass being accelerated and provides a means of measuring displacement
vs. time. Used a lot in lower level physics labs when teaching laws of
motion.

Now we just have fast cameras or direct measurement of acceleration and
velocity.
