Forces - Physics

  • Pressure
    • Force = pressure x Area
    • N = Pa x m2
    • Pressure can be measured in Pa and N/m2
    • Particles in liquids are virtually incompressible
    • The pressure in liquids is transmitted equally in all directions
    • Hydraulics - The pressure in the master piston is the same as that in the slave piston
    • Hydraulics are used in buses to allow the step to be lowered
