PENGEMBANGAN ALAT PRATIKUM GERAK LURUS BERUBAH BERATURAN

A comprehensive understanding of physics, particularly Uniformly Accelerated Linear Motion (GLBB), is crucial in mechanical engineering, as it significantly influences the design and analysis of mechanical systems. This study aims to create a practical tool to demonstrate GLBB the research employed an experimental method, examining 12 samples through a Research and Development approach. The performance of the tool was evaluated by comparing its measured values with theoretical calculations at various inclination angles (0°, 15°, 30°, and 45°), while maintaining a constant travel distance of 80 cm. The results revealed that acceleration increased from 0.551 m/s² at 0° to 6.996 m/s² at 45°, while travel time decreased from 1.74 seconds at 0° to 0.48 seconds at 45°. Validation of the results showed a minimal difference in acceleration of 0.003 m/s², with a percentage deviation of 0.547%, and a time difference of 0.032 seconds, with a percentage deviation of 1.872%, indicating the tool's high accuracy. Moreover, the tool demonstrated a high degree of precision, achieving an accuracy of 98.75% in measurements at a 0° angle, confirming its effectiveness in accurately and precisely capturing GLBB parameters. It is recommended that further development focus on optimizing the design, utilizing high-precision materials and sensors, and conducting additional experiments with varying inclination angles, travel distances, and object masses to enhance the tool's accuracy and reliability across different experimental conditions.
