Acceleration Spark Timer
* #2008 Acceleration, Spark Timer.
This apparatus is used for determining the rate of acceleration in a falling weight, calculating the speed of a moving cart or studying the forces of friction.  A paper strip is pulled through the timer while a spark at a very precise interval is created which burns tiny dots into the paper strip as it passes.  The faster the strip passes through the sparks the larger distance between dots.  It is easy then for the student to calculate the rate of speed for acceleration.  As an added benefit, everything on the spark timer is enclosed for safety.  Instructions included.
