Abstract

This study aims to analyze the acceleration of gravity (g) in free fall with a height of 2 meters using a video tracking application. This research is located in the Department of Geological Engineering, Pattimura University, Ambon. The method used in this research is the experimental method. The tools and materials used in this study were tennis balls (2 grams), baseball (80 grams), roll meter, camera and laptop. Based on the results of data analysis, it was found that the value of gravitational acceleration at a height of 2 meters for samples of tennis balls (2 grams) and baseballs (80 grams) was 9.67 ± 0.27 m/s2 and 9.60 ± 0.27 m/s2.

Abstract

This research aims to analyze the effect of load mass on the damping coefficient of liquid substances such as water, cooking oil, and oil. The load masses used are 71 grams, 81 grams, 91 grams, and 101 grams. This study employs an experimental method with a damped oscillation analysis approach aided by Origin software. The research results indicate a significant influence of load mass on the frequency (Hz) and damping coefficient (γ) values of the liquid substance, where the larger the load mass, the higher the frequency (Hz) and damping coefficient (γ) values of the liquid substance. The study also examines the damping constants of each liquid substance. The results show that the damping constants of each liquid substance, namely water, cooking oil, and oil, are respectively 0.049 kg/s, 0.107 kg/s, and 0.201 kg/s.
