There are 2 lessons in this physics tutorial covering Liquid Pressure. Pascal's Principle. The tutorial starts with an introduction to Liquid Pressure. Pascal's Principle and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Liquid Pressure. Pascal's Principle. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• The meaning of liquid pressure
• The factors affecting liquid pressure
• The other name used for water pressure
• How can we use U-shaped tubes to find the density of unknown liquids
• What does Pascal's Principle say?
• How can we use the Pascal's Principle in practice?

## Introduction

Why do you feel a light pain in the chest when you go for the first time at beach?

Why people cannot dive so deep in water even though they may have oxygen cylinders with them?

Do you think it is important the position of an object inside water if the depth doesn't change?

Do you think the situation changes when you replace water with another liquid in the above examples?

All the above questions relate to the concept of liquid pressure, which will be explained in this tutorial.
