Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area.

SI Unit : Pascal

• There are various types of pressure including Absolute, Atmospheric, Differential, and Gauge Pressure.
• Along with solids, fluids also exerts pressure.
• Pressure is highly dependent on area. Lesser the area, higher is the pressure.
• The primary formula for pressure is P = F/A.
