CONCEPTS

The effect of a force pushing on a surface depends on the size of the force and the area it is pushing on.

Pressure is measured in Force(in Newtons) divided by area (in mē). This gives an answer in N/mē or Pascals (Pa)

Liquid pressure increases with depth, and acts uniformly in all directions

LESSONS

Hydraulic systems (brakes, ram, lifts)

Atmospheric pressure (collapsing can /Magdeburg hemispheres)

Measuring atmospheric pressure using a garden hose

Lung pressure
