GSC International N-00030 Spark Timer with 60Hz single function. Made by Narika Corporation. This high-precision tool supports educators in demonstrating core physics principles effectively while fostering active learning and critical thinking among students.Precision in Linear and Free-Fall Motion AnalysisThe Spark Timer allows educators and students to observe and verify Newton's 2nd Law in action. By using a heat-sensitive ticker tape, the timer creates double dots at fixed intervals, enabling precise calculation of speed and acceleration in dynamic cart or free-fall experiments.High-Speed Performance with Bold DelimitersThe device accommodates high-speed movements, ensuring clear dot markings on the tape. Bold double dots appear at every 10 Hz interval, simplifying tape segmentation and analysis for both linear and a
