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 m 1 of 0.01 kg, 0.02 kg, 0.03 kg, by using weights m 2 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%.
