_{Definition:
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.
