Paineet
Paineet is the Finnish word for pressures and is used in physics and everyday language to describe the forces exerted per unit area on surfaces. In physics, pressure is defined as the perpendicular force per unit area: P = F/A. It is a scalar quantity that describes how concentrated a force is over a given area. In fluids, pressure exists within liquids and gases and can vary with depth or position.
Different types of pressure include absolute pressure, which is measured relative to a perfect vacuum; gauge
Measurement devices include barometers for atmospheric pressure, manometers for pressure differences, and sphygmomanometers for measuring blood
In gases, pressure relates to temperature and volume through gas laws; changes in temperature or volume can
