Abstract
ABSTRAK
Penelitian tentang gerak lebih banyak dikaitkan dengan pengukuran kecepatan dan percepatan, sangat sedikit yang dikaitkan dengan gaya. Hal ini karena terkendala ketersediaan alat ukurnya. Sebagai alat ukur gaya, neraca pegas biasa digunakan untuk keadaan statis. Untuk itu tlah dilakukan pengukuran gaya pada sistem yang berosilasi menggunakan neraca pegas dengan bantuan video. Penelitian ini menggunakan dua neraca pegas yang diikatkan pada dua benda. Sistem ini diletakkan di atas air track yang dipasang miring. Neraca pegas pertama dihubungkan pada suatu tiang tetap. Kedua benda dihubungkan dengan tali. Selama benda bergerak skala kedua neraca pegas direkam menggunakan smartphone. Hasil rekaman video kemudian diolah menggunakan perangkat lunak Logger Pro. Hasil analisa gaya pada neraca pegas pertama menunjukkan gejala osilasi yang teredam. Neraca pegas kedua menunjukkan hubungan tegangan tali terhadap posisi benda yang berbentuk grafik linear. Eksperimen ini menunjukkan bahwa neraca pegas yang biasanya digunakan untuk pengukuran gaya yang statis dapat digunakan juga untuk keadaan dinamis.
Kata kunci—neraca pegas, gaya, Analisa video
ABSTRACT
Force measurement on an oscillating system have been performed using two spring balances and video analysis. This study employed two spring balances attached to two carts. The system was placed on an inclined air track. The first spring balance was connected to a fixed post. A rope was used to connect the two carts. Two smartphones were used to record the scale changes of the two spring balances. The recorded video was then processed using Logger Pro software. The results of the force analysis on the first spring balance indicated damped oscillation phenomena. The second spring balance revealed a linear relationship between the rope tension and the cart's position.
