Three Stage Frequency Spark Timer Kit

Spark Timer Kit is designed for use to measure the speed of a moving cart, investigate the forces of friction in dynamics, or determine the rate of acceleration in a falling body at a vertical position. The spark generator creates a series of sparks which burns tiny dots into the paper tape at a precise and same interval when the tape is pulled through the Spark Timer. The faster the tape is pulled through the timer, the larger the distance between the dots.This allows students to calculate the speed and acceleration of the object. The recording needle is immediately raised when the timer is turned off to allow easy insertion or removal of tape.

Spark Timer Kit, Three-stage frequency B is equipped with 20Hz, 60Hz and 100Hz settings that provide clear print, even for a relatively slow-moving dynamic cart.

Spark timer kit comes with 120a of recording paper tape, Pack of 10 carbon discs, a table clamp, and a 300g weight.

Note: Since this distance is usually very small; it is necessary to measure the distance moved in 10- tick interval and devide this by the time for covering the 10- tick interval.
