Description
Application to Pascal’s Law – Drum Break
In this interactive moment, students can notice the drum brake, as an application of Pascal's law.
Fundamental Principle of Hydrostatics
This interactive moment shows students how to calculate the difference of pressure between two points of a liquid in equilibrium.
Factors the Static Pressure Depends On
This interactive moment presents the factors that can influence the pressure. Students are asked to move the manometer capsule in order to find out what exactly influence the pressure.
Hydrostatic Pressure - Properties
This lesson moment explains how hydrostatic pressure acts upon the container's walls due to the liquid's weight.
Applications to Pascal’s law – Hydraulic brake
This lesson moment explain how the disk brake works and presents its components along with their role.
Applications of Pascal’s law – Pascal’s Barrel
This lesson moment teaches students how they can break a barrel with only 2l of water due to Pascal's law.
Applications - Barometer
This interactive application shows students how does the barometer work and teaches them how to build one.
Pressure of a Gas. Air Pressure
This interactive application shows students how the air pressure increases in a balloon, thus its size increasing.
Applications – Communicating Vessels (1)
This application teaches students that the liquid in communicating vessels remains at the same level not depending on the vessels' size or height.
Communicating Vessels
Student can learn from this lesson moment how the principle of communicating vessels works.
