Gerak Harmonik Sederhana Pada Pegas Dapat Digunakan Untuk Membuktikan Nilai Percepatan Gravitasi Bumi

This research was conducted to prove the value of Earth'sgravitational acceleration. This research was conducted inJuly 2015 until September 2015. The research method usingthe experimental method in the spring in this case used 2different types of springs that are both long and constant. Inthis experiment the observed variables are the period ofvibration and the change in spring length. Measuring thelength of the springs is done as much as 5 times for differentload masses. Each load is hung and vibrated by 20 vibrationsto obtain vibration period data. The results obtained that thevalue of the acceleration of gravity is 9.8 m/s2. The Result ofthis research concluded that the acceleration of Earth'sgravity depends on the spring period and the increase inspring length.Keywords: earth's gravitational acceleration, spring period
