Ch 24: AFOQT: Thermodynamics & Electricity

About This Chapter

Review the basics of thermodynamics and electricity as you review for the Air Force Officer Qualifying Test. After using the engaging video and text lessons to study, you can test your knowledge with the corresponding lesson quizzes.

AFOQT: Thermodynamics & Electricity - Chapter Summary

The focus of these lessons is thermodynamics and electricity, which are topics that may be assessed on the AFOQT exam. Reviewing the information in this chapter can help you review the following:

  • Nature and significance of energy
  • Kinetic energy to potential energy
  • Thermal, nuclear, electrical, chemical, radiant and mechanical energies
  • Laws of thermodynamics
  • Electric charge and force
  • Ohm's Law
  • Electrical resistance
  • Electric current and potential

Each concept is taught by professional instructors through short videos that have interactive timelines. The interactive timelines allow you to maneuver through the videos to review specific contents when necessary. After you have viewed the lectures, you can use the self-assessment quizzes to check your learning.

What is Energy? - Definition and Significance in Nature

1. What is Energy? - Definition and Significance in Nature

This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

2. Kinetic Energy to Potential Energy: Relationship in Different Energy Types

This video defines and describes kinetic and potential energy. You'll learn how different types of energy can be classified as potential and kinetic. You'll also find out how kinetic and potential energy are transformed.

First Law of Thermodynamics: Law of Conservation of Energy

3. First Law of Thermodynamics: Law of Conservation of Energy

This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.

Second Law of Thermodynamics: Entropy and Systems

4. Second Law of Thermodynamics: Entropy and Systems

In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.

What is Mechanical Energy? - Definition & Examples

5. What is Mechanical Energy? - Definition & Examples

In physics, energy is how work gets done. This video describes one important type of energy, mechanical energy, and provides examples of both kinetic and potential mechanical energy.

What is Thermal Energy? - Definition & Examples

6. What is Thermal Energy? - Definition & Examples

This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.

What is Radiant Energy? - Definition & Examples

7. What is Radiant Energy? - Definition & Examples

This lesson defines and describes radiant energy in its different forms. The different types of electromagnetic waves created by radiant energy are identified and described as well. This includes X-rays, microwaves, and radio waves, to mention a few.

What is Chemical Energy? - Definition & Examples

8. What is Chemical Energy? - Definition & Examples

This lesson describes chemical energy as a type of potential energy stored in chemicals, such as sugar and gasoline. The lesson discusses how energy is transferred from solar energy to chemical energy by plants and how gasoline is a source of chemical energy used to move cars.

What is Nuclear Energy? - Definition & Examples

9. What is Nuclear Energy? - Definition & Examples

You've probably heard of nuclear energy. But what is it? And what is the difference between fusion and fission? This lesson will answer your questions about this exciting form of energy that involves atoms and their nuclei.

What is Electrical Energy? - Definition & Examples

10. What is Electrical Energy? - Definition & Examples

This lesson defines electrical energy and explores its role as a form of potential energy. It also offers an explanation of how it functions within electric fields and provides examples of its applications.

Electric Charge and Force: Definition, Repulsion & Attraction

11. Electric Charge and Force: Definition, Repulsion & Attraction

Have you ever wondered what electricity is and where it comes from? Have you ever been zapped by static electricity and wondered how it got there? We'll answer all of these questions in this lesson on electric charge and force!

Electric Potential: Charge Collections and Volt Unit

12. Electric Potential: Charge Collections and Volt Unit

In this lesson, we'll find out that electric charges can be rather lazy until something motivates them to get work done. Find out what gives electric charges the potential to do work and how we measure that potential with something called voltage.

What is Electric Current? - Definition, Unit & Types

13. What is Electric Current? - Definition, Unit & Types

Like a river current is the flow of water molecules, electrical current is the flow of charged particles. In this lesson, we're going to explore what electrical current is, what causes it, and that, unlike a water current, electrical current doesn't always flow in one direction.

Electrical Resistance: Definition, Unit & Variables

14. Electrical Resistance: Definition, Unit & Variables

We'll take a shopping trip to the mall to learn how electrical resistance works and how it is affected by resistivity, conductor dimensions, and temperature. We'll also take a look at several common appliances that take advantage of resistance to function.

Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

15. Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

Did you know that electrical current is affected by the voltage and resistance in a circuit? In this lesson, we'll use Ohm's law, which tells us how current, voltage, and resistance are related, as we work through several electric circuit examples.
