Pressure is the force exerted, by a substance, per unit area.
Explanation:
Pressure is given by the formulae;
P = F/ A
Whereby;
P = pressure
F = Force
A = area
Remember that ..
F = Ma
Whereby;
F = Force
M = mass
a = acceleration
Therefore pressure can be given as;
P = Ma / A
The mass of the above column of a substance multiplied by the acceleration due to gravity = pressure exerted by the substance.
