Question

Define the term 'pressure'. Describe some examples of pressure from everyday life.​

Answer 1

Definition

Pressure is defined as a measure of the force applied over a unit area.

Simple Example of Pressure

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.

Other examples

1.The air filled in car tires lifts the whole car weight.

2."Sucking a drink" through a straw -" fluid flows because" of the pressure difference.

3.The flying of aircraft due to the "pressure on the wings".

4."Small bullet fired" from a gun" with pressure.

Answer 2

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). Unit of pressure is Pascals (Pa).

Examples of pressure from everyday life:

1. The air filled in car tires lifts the whole car weight.
2. Sucking a drink through a straw
3. Toy balloon inflates because of air pressure inside
4. Aircraft fly because of the air pressure on the wings.
