button is set at a high current. The blades spin faster represents the greater force produced
by the motor of the fan.

EKSPERIMEN : INERSIA


INFERENS : Inersia dipengaruhi oleh jisim objek

HIPOTESIS : Jika jisim bertambah, maka inersia bertambah

TUJUAN : Untuk mengkaji hubungan antara jisim dan inersia

PEMBOLEHUBAH : Manipulasi : Jisim, m
Bergerakbalas : Tempoh ayunan, T
Dimalarkan : Jarak antara bebola plastisin dan apit-G, // Sudut ayunan, q

RADAS DAN BAHAN : Apit G, plastisin, bilah gergaji, penimbang elektronik, jam randik, pembaris













PROSEDUR : 1. Sediakan radas seperti rajah
2. Mula eksperimen dengan melekatkan bola plastisin berjisim, m = 50 g pada hujung
mata gergaji. Sesarkan bilah gergaji pada sudut, q = 45
