About This Chapter
Understanding Fluids in Physics - Chapter Summary
Let us help you study up fluids in physics. Our instructors have developed lessons that will help you understand formulas for measuring the properties and functions of fluids. After completing the lessons, you will have reviewed:
- Characteristics of fluids in physics
- Density, pressure and hydrostatic pressure
- Determining buoyancy
- Using the continuity equation for fluid mass and flow rate
- Bernoulli's principle and equation
- Torricelli's theorem and examples
We strive to make the learning experience exciting and effective. Our instructors have developed the lessons to provide you with several methods for staying engaged and retaining the information. Each lesson contains a compelling video to help illustrate the material. There are self-assessment quizzes available throughout the chapter for you to test your knowledge. You can track your progress through the chapter on your Dashboard. After completing all of the lessons, take the cumulative chapter exam to see how well you've absorbed the information.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
