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).

Explanation:

What is Pressure?

The pressure is the physical force applied on an object in the perpendicular direction to the surface on its unit area. Its basic formula is dividing the force by the area of the surface. Its unit of measurement is Pascal (Pa). Pressure exists in various forms in nature and our surroundings. The main types of pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.

In our daily life, we may easily find many phenomena that are related to pressure. For example, while sipping beverages from a straw, we actually suck the air out of the straw. And while we sip the beverage, we are actually applying the pressure. The SI unit for pressure is the pascal or Newton per square meter. Some other units are also there like pounds per square inch and bar etc.

EXAMPLES;

The air filled in car tires lifts the whole car weight. "Sucking a drink" through a straw -" fluid flows because" of the pressure difference. The flying of aircraft due to the "pressure on the wings"
