Abstract

Abstract: The aim of this study was to determine the feasibility of automatic time-lapse-based Atwood aircraft tools to explain Newton's second law. The method in this research was the experimental method. Instrument testing was carried out at mass loads m1 of 0.01 kg, 0.02 kg, 0.03 kg, by using weights m2 of 0.1 kg at a distance 60 cm and force variations of 0, 5 N, 0, 6 N and 1 N. The results of the measurement and analysis of the data obtained acceleration in theory Newton's second law, namely each for mass variants and successive forces is 4.864 m/s 2, 4.102 m/s 2, 3.414 m/s 2, 2.069 m/s 2, 2.581 m/s 2 and 4.102 m/s 2 . The results of the acceleration calculation are based on an automatic time interval 4.220 m/s 2, 3.826 m/s 2, 2.985 m/s 2, 1.697 m/s 2, 2.415 m/s 2 and 3.826 m/s 2 . The smallest error data is 6.39% and the biggest error is 18%. The results of these measurements indicate the measurement is still accurate because the error percentage is less than 20%.
