Abstract

An equipment for an object motion analysis base on time measurement has successfully developed by use a micro processsor”arduwino” for time measurement. The micro processor as a time measurement is controlled by the output signal of photo diode. By means of this equipment was obtained the time measurement accuracy up to three decimal places. When this equipment used to measure the gravity acceleration in our laboratory by means free fall of an object we obtained the value of 9.8570.035 (m/s2) in ten times measurement. Another advantage of this equipment is to study the terminal velocity when an object move in liquid.

Keywords: motion quanties; micrpprocessor; photo diode; terminal velocity; liquid.
