2.1 Tujuan Praktikum Mengukur besar percepatan gravitasi (g) dengan menggunakan simple pendulum 2.2 Alat yang digunakan Set alat bandul matematis Stop wach Mistar 2.3 Teori Bila suatu bandul diberi simpangan sudut dari posisi setimbang dankemudian
T = 2 π
l g
Dimana : l : Panjang tali g : Percepatan gravitasi di tempat percobaan Gambar 2. 1 M 2.3.1 Grafik Langkah – langkah membuat grafik
( Σy − b Σx )
2.7 Tugas Akhir
Grafik antar I dan T² Y = T² (Periode waktu /T²) Gambar 2. 3 Grafik antara I dan T^2 Adapun cara untuk mendapat gravitasi ditempat percobaan adalah g =^4 π^ 2 l T 2 g = 4 (3,14)
2 g = 1, jadi hasil dari percepatan gravitasi di tempat percobaan saya adalah 1,072 m/s^2
menunjukan adanya keakuratan pada alat dan bahan yang digunakan, sehingga mendekati harga gravitasi yang sebenarnya. Yaitu sebesar 9,8 m/s2.
