Question

what is pressure?
with eg​

Answer 1

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). ... Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure. A simple example of pressure may be seen by holding a knife to a piece of fruit. ... If you turn the blade so the cutting edge is pressed into the fruit, the same force is applied over a much smaller surface area (vastly increased pressure), so the surface cuts easily.
