Pressure can be calculated if you know the force applied to or by an object and the contact area. The units are newtons per square meter, or N/m2.
Demo
In this tutorial you will learn how to calculate the pressure exerted by an object if you have been given the force applied to the object and given area.
The equation for this calculation is written like this:
$P = { \text F \; \text / \; \text A}$
Chilled practice question
The base of a brief case has an area of 25 cm 2 and a mass of 5 Kg. Calculate the pressure exerted by the briefcase when placed on a surface. Take the force of Gravity as 10N/Kg.
Frozen practice question
An elephant exerts a pressure of 53500 N/m2 one of its feet has an area of 0.15 m2. Calculate the mass of the elephant. Take the force of Gravity as 10N/Kg.
Science in context
Pressure can be calculated if you know the force applied and the area using the physics equation, P = F/A. Pressure is equal to force divided by area, units are newtons per square meter, or N/m2.
