Question

investigate the relationship P=F/A

Answer 1

Explanation:

Derivation

P = Pressure in Pascal

F = Force on the object

A = Area on which the force act

Besides, we often calculate pressure for gases and fluids. In those conditions, the pressure of liquid or gas is equal to the density of that fluid multiplied by the acceleration due to the gravity and the height (depth) of the fluid above a certain point.

Pressure = density of fluid × acceleration due to gravity × height of the fluid column

P = ρ ×g × h
