The S.I. unit of pressure is ___

Unit S.I. tekanan ialah ___

• Pascal (Pa)

• Newton (N)

• Joule (J)

• Kilogram (kg)

What is the equation used to calculate pressure?

Apakah persamaan untuk menghitung tekanan?

• Pressure = Mass / Volume

  Pressure = Jisim / Isi padu

• Pressure = Area / Force

  Tekanan = Luas / Daya

• Pressure = Force / Area

  Tekanan = Daya / Luas

• Pressure = Force / Mass

  Tekanan = Daya / Jisim
