- Pressure: the force acting perpendicularly on unit area.
- Force (F): the push or pull on an object, measured in newtons (N).
- Area (A): the size of the surface the force acts on, measured in square metres (m²).
- Pascal (Pa): the unit of pressure. 1 Pa = 1 N/m².
- Perpendicular: meeting the surface at a right angle, that is, pushing straight into it.
- One pascal: the pressure produced when a force of 1 N acts on an area of 1 m².
