1. What is Energy? - Definition and Significance in Nature
Energy is the capacity or ability to perform work, which is significant in causing anything to move within nature. Explore the different types of energy, where it comes from, why it is necessary, and how it is important in natural systems.
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.
3. What is Mechanical Energy? - Definition & Examples
Mechanical energy can be defined by the energy possessed by an object. Explore the two forms of mechanical energy, examples of mechanical energy, and discover the definitions of energy and work.
4. What is Chemical Energy? - Definition & Examples
Chemical energy is energy that is stored in chemicals. Look at some examples, such as sugar and gasoline, and learn about the importance of chemical energy in everyday life, and the functions of exothermic and endothermic reactions.
5. What is Electrical Energy? - Definition & Examples
Energy comes in many different forms, including electric energy, which is found in charged particles in an electric field. Learn more about the definitions of energy and electrical energy, how electrical energy functions, and how electrical energy is applied.
6. What is Radiant Energy? - Definition & Examples
Radiant energy exists in various forms, including electromagnetic waves. Learn about the definitions of radiant energy, electromagnetic waves, and high and low energy waves, before seeing some examples of how radiant energy is applied in our everyday lives.
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.
8. Kinetic Energy to Potential Energy: Relationship in Different Energy Types
Kinetic energy and potential energy are created differently. In this lesson, we will dive into different types of energy, and how they can be transformed into other types of energy.
9. Chlorophyll: Absorbing Light Energy for Photosynthesis
In photosynthesis, chlorophyll and other pigments absorb wavelengths from sunlight, which excites the electrons contained in them. Discover the process of how light energy is absorbed by chlorophyll and why it is important for the next steps of photosynthesis.
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.
11. First Law of Thermodynamics: Law of Conservation of Energy
The first law of thermodynamics, also known as the law of conservation of energy, says that energy cannot be created or destroyed. Explore the first law of thermodynamics, see how energy can only be transformed but not created or destroyed, and discover some examples of the practical application of this law.
12. Renewable & Non-Renewable Resources: Definition & Differences
Resources naturally replenished by the environment are Renewable Resources, whereas those which replenish too slowly for use, or not at all, are non-renewable. Explore the implications and differences of these two resource types.
13. What Are Fossil Fuels? - Definition, Advantages & Disadvantages
Fossil fuels are sources of energy that developed within the Earth over millions of years. The three main types of fossil fuels are coal, oil, and natural gas. Explore the definition of fossil fuels, and learn about their creation, how they are used as energy, and their advantages and disadvantages.
14. What is Solar Energy? - Definition, Pros & Cons
The sun produces energy called solar energy. Learn about photons, electromagnetic waves, solar cells, as well as the advantages and disadvantages of solar energy, and discover how life on Earth is reliant on solar energy.
15. Wind as a Renewable Energy Resource: Advantages & Disadvantages
Wind power is a renewable energy resource, but there are both pros and cons to this type of energy. In this video lesson, you will learn about wind power as well as some of the benefits and drawbacks of using it as a global energy source.
16. Hydroelectric Energy: Definition, Uses, Advantages & Disadvantages
In this video lesson you will understand how water can be used to generate electrical energy. You will also identify some benefits and drawbacks of using this type of renewable resource for energy production.
17. Geothermal Energy: Advantages and Disadvantages
Geothermal energy originates from within the Earth's crust that can be used to produce electricity or for heating. Learn more about geothermal energy, including heat pumps and power plants, and explore the advantages and disadvantages of relying on it.
18. Biomass for Renewable Energy: Pros and Cons
Biomass is organic matter found in animals and plants that can be used as a renewable energy source. Learn about biomass energy, and understand the processes for converting biomass to energy, including co-firing, gasification, and fermentation. Explore the pros and cons of biomass energy, such as its abundant availability as well as cost barriers.
19. Kinetic Energy: Examples & Definition
Kinetic energy is a form of energy due to motion, and it varies depending on the mass and the speed of the object in motion. Explore the different types and the factors that affect kinetic energy.
