Understanding Pressure (Memahami Tekanan)

  • Pressure is defined as force per unit area. therefore, the smaller the area, the higher the pressure.
  • The SI units for pressure are Newtons per square metre (N/m2), now called Pasals (Pa) ( 1 N/m2 = 1 Pa). 
  • You can also use Newtons per square cm (N/cm2).
  • The pressure between two solid surfaces depends on two things:
                (a) the force between the surfaces
                (b) the area of contact between the two surfaces.

  • The greater the force or the smaller the area the greater the pressure.
  • The pressure of a given force increases as the surface area decreases.
