Write down the relation between force pressure and area

Pressure is directly proportional to force and inversely proportional to area.

Explanation: Pressure is defined as the ratio of force applied to the area of cross section.

Mathematically,

P=\frac{F}{A}P=

A

F

where,

P = Pressure

F = Force applied

A = Area of cross-section

from above it is visible that pressure is directly proportional to the force applied which means that if force increases, pressure increases. It is also inversely proportional to the area of cross-section. So, when area of cross-section increases, pressure decreases.

The units of pressure are N/m^2N/m

2

and S.I. units for this term is Pascal (P).
