Gerak Harmonik Pada Pegas – Penjelasan dan Rumus

Contoh benda yang dapat melakukan gerak harmonik adalah benda yang digantungkan pada pegas kemudian digetarkan (getaran pegas) dan benda yang digantung dengan tali kemudian diberi simpangan kecil dan diayun (ayunan sederhana). Perhatikan kegiatan tentang getaran pegas yang diilustrasikan pada gambar 3.7 berikut.

Gambar Getaran Pegas Keterangan:
Gambar 3.7 (a) : Sebuah beban dengan massa m digantungkan pada pegas dengan konstanta gaya K dan beban setimbang di titik B

Gambar 3.7 (b) : Beban ditarik sampai ke bawah sampai di titik A sejauh y Pada saat itu timbul gaya pegas F = K.y dengan arah menuju titik setimbang (ke atas) sehingga pada saat beban dilepaskan beban bergerak ke atas sampai melampaui titik setimbang.

Setelah beban melampaui titik setimbang arah gaya pegas ke bawah (ke arah titik setimbang). Setelah beban sampai di titik C, beban bergerak ke bawah, selanjutnya beban bergerak harmonik. Gaya penggetar selalu mengarah ke titik setimbang.

Kerjakan soal berikut!
1. Periode getaran harmonik pegas di bumi = 30 sekon. Berapakah periode getaran harmonik pegas tersebut bila diletakkan di bulan? (Percepatan gravitasi di bumi = 6 kali percepatan gravitasi di bulan)
2. Sebuah pegas pada saat ditarik sehingga bertambah panjang 2 cm mempunyai energi potensial 10 Joule. Berapakah energi potensial pegas tersebut jika pegas ditarik sehingga bertambah panjang 4 cm?
