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.

Work-Energy Theorem: Definition and Application

2. Work-Energy Theorem: Definition and Application

Work and energy are closely related in physics. In this lesson, you'll learn what that relationship is as well as how we can apply it to various situations.

What is Mechanical Energy? - Definition & Examples

3. 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 Chemical Energy? - Definition & Examples

4. 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 Electrical Energy? - Definition & Examples

5. 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.

What is Radiant Energy? - Definition & Examples

6. 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 Nuclear Energy? - Definition & Examples

7. 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.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

8. 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.

Chlorophyll: Absorbing Light Energy for Photosynthesis

9. Chlorophyll: Absorbing Light Energy for Photosynthesis

Plants are clean, green, photosynthesizing machines. Using a specialized pigment called chlorophyll, plants are able to soak up energy from the sun and turn it into food. In this lesson, we'll start to learn why chlorophyll literally gets excited about a sunny day!

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

10. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.

First Law of Thermodynamics: Law of Conservation of Energy

11. 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.

Renewable & Non-Renewable Resources: Definition & Differences

12. Renewable & Non-Renewable Resources: Definition & Differences

We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.

What Are Fossil Fuels? - Definition, Advantages & Disadvantages

13. What Are Fossil Fuels? - Definition, Advantages & Disadvantages

Fossil fuels are sources of energy that have developed within the earth over millions of years. Because fossil fuels - oil, natural gas, and coal - take so long to form, they are considered nonrenewable. Learn more about these fuels, including the pros and cons of using them.

What is Solar Energy? - Definition, Pros & Cons

14. What is Solar Energy? - Definition, Pros & Cons

Learn about solar energy and how charged particles from the sun travel to Earth to provide heat and light. Explore solar energy as a direct and indirect energy source and examine the pros and cons of harvesting solar energy for other uses.
