## Students will review:

In this chapter, you'll learn the answers to questions including:

- What are the definitions of density and pressure?
- How does the hydrostatic pressure equation work?
- How is Archimedes' Principle used to calculate buoyancy?
- What are the guiding principles behind Torricelli's theorem?
- How can Bernoulli's and the continuity equations be applied to fluids in motion?

### 1. What Is Density? - Explanation & Examples

After watching this video, you will be able to explain what density is, give examples of high and low density, and calculate density using an equation. A short quiz will follow.

### 2. Pressure: Definition, Units, and Conversions

Have you ever wondered what pressure is and how it gets measured? In this lesson, we are going to define pressure and explain some of the units that are used to express measurements of pressure.

### 3. Hydrostatic Pressure: Definition, Equation, and Calculations

This video lesson will introduce you to hydrostatic pressure in a liquid, as well as provide examples for how to calculate the liquid's pressure at a given depth.

### 4. Fluid Mass, Flow Rate and the Continuity Equation

Fluids rarely stay put, so we need to understand how they move. In this lesson, you will learn about how the movement of fluids is influenced by the space it passes through, as well as see examples of how to calculate aspects of this movement.

### 5. Bernoulli's Principle: Definition and Examples

Understanding how a moving fluid's speed and pressure change as it flows along is not only important for building airplanes but also for backyard fun. In this video lesson you'll learn about Bernoulli's principle and identify some practical applications of this concept.

### 6. Bernoulli's Equation: Formula, Examples & Problems

Bernoulli's equation describes an important relationship between pressure, speed, and height of an ideal fluid. In this lesson you will learn Bernoulli's equation, as well as see through an example how in an ideal fluid, the dynamics of that fluid remain constant.

### 7. Buoyant Force: Definition, Equation & Examples

This lesson defines the buoyant force, and it explains where buoyant force comes from and where it exists. It describes the different kinds of buoyancies while giving you a formula and an example of this force.

### 8. Johann Bernoulli's Contributions to Math: Biography & Concept

Johann Bernoulli was a Swiss mathematician who lived from 1667-1748. In this lesson, you will learn more about Bernoulli and his contributions to the field of mathematics, and take a quiz covering the highlights of his career.

### 9. What is Viscosity? - Definition, Measurement & Equation

In this lesson, you will learn about viscosity - what it is, how it is measured, and the equation needed to figure out the viscosity of a fluid. You'll also discover the reasons why viscosity is important.

### 10. The Law of Universal Gravitation: Definition, Importance & Examples

Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.

### 11. What Are Simple Machines? - Definition, Types & Examples

If you need to move or lift a heavy object, it would be wise to use a simple machine. Though these devices are far from fancy or high-tech, they are extremely helpful for getting work done.

### 12. Fluids in Physics: Definition and Characteristics

Fluids really know how to move! As flowing materials, fluids have some unique properties that help us understand and describe them. In this lesson you'll explore what fluids are and how they are defined in the world of physics.

### 13. Buoyancy: Calculating Force and Density with Archimedes' Principle

Knowledge of the buoyant force is important when trying to understand why some objects float while other objects sink. In this lesson you'll learn about this unique force and how we apply it to various situations using Archimedes' Principle.

### 14. Torricelli's Theorem: Tank Experiment, Formula and Examples

Torricelli's theorem has practical applications in everyday life. This physical law explains an important relationship between fluid exit velocity and the height of that fluid in a container. Here, you will learn about this relationship as well as see how to calculate exit velocity using Torricelli's theorem.
