Answer 1

Answer:

• 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). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure

Answer 2

$\textbf{Answer:-}$

What is Pressure?

• The amount of force exerted (thrust) on a surface per unit area is defined as ‘Pressure’. It can also be defined as the ratio of the force to the area (over which the force is acting).

Formula and Unit of Pressure

• Pressure (P) = Thrust/ Area.

The SI unit is ‘pascals (Pa)’. 1 Pa

$= 1N/ {m}^{2}$

Example:-

It is easier to hammer a sharp pin than to hammer a blunt pin. This is because the area at the end of the sharp pin is smaller than the area at the end of a blunt pin. This leads to an increase in pressure leading to hammer the sharp pin easily.
