Question

define pressure with examples​

Answer 1

Answer:

• Force acting on a unit area is called pressure.
• pressure = force/area
• SI unit of pressure is pascal (pa)

A simple example of pressure may be seen by holding a knife to a piece of fruit. If you hold the flat part of the knife against the fruit, it won't cut the surface. The force is spread out of a large area (low pressure). 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.

Answer 2

Explanation:

pressure is defined as the physical force exerted on an object. the force applied is perpendicular to the surface object per unit area. the basic formula of pressure is F/A. unit of pressure is Pascal.
