Pressure refers to the force exerted per unit area on the surface of an object or substance. It is a scalar quantity that is measured in units such as pascals (Pa) or pounds per square inch (psi).

Key Points:

  • Pressure is the result of a force distributed over an area.
  • The formula for pressure is: Pressure = Force / Area.
  • Pressure is directly proportional to the force applied and inversely proportional to the area over which the force is distributed.
  • Pressure can be transmitted through fluids and is responsible for various phenomena such as buoyancy, hydraulic systems, and atmospheric pressure.
  • Pressure can be measured using instruments such as pressure gauges or manometers.
  • Pressure is an important concept in physics, engineering, and many other fields.
