THE TICKER TAPE TIMER

The ticker tape timer

At a glance this apparatus have no any arrived in freshmen students especially if students have no experience in a physics laboratory. This very simple rectangular black apparatus with switch was used to detemine the acceleration of an object moving down an incline plane or dynamic track.

It is sometimes called recording timer. It leads in the realization of the distance covered by an object under accelerated motion increases for same time interval.

This device is operated on a low voltage AC supply of usually 60 HZ. However the experiment done in the Laboratory has only 10 HZ and 40 Hz. This device also serves as vibrator which leaves dots on a paper tape using a carbon paper.
