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.
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.
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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. How to Calculate Specific Heat Capacity for Different Substances
This lesson describes specific heat capacity and explains how the specific heat capacity of water helps to maintain a relatively constant temperature in nature. Learn how to identify the specific heat capacity of other common materials and how to calculate specific heat capacity with an experiment.
10. Changes in Heat and Energy Diagrams
Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.
11. Energy and Life: The Transformation of Energy in Living Organisms
While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.
12. The Kinetic Theory of Matter: Definition & The Four States of Matter
Everything on Earth is made of matter, but that matter isn't always the same. Matter can exist in four different phases, and the kinetic theory of matter helps us understand the differences between those phases.
13. What is Electric Energy? - Definition, Sources & Examples
Electricity is all around us, but where exactly does it come from? In this lesson, you'll explore the most basic source of electric energy and understand how this electron movement provides something that we often take for granted in our modern lives.
14. What is Physics? - Definition, History & Branches
Known as the fundamental science, physics creates a foundation for other natural sciences. In this lesson, you'll be introduced to the field of physics, learning about its history and its modern branches of study.
15. What is Steam Energy? - Definition & Examples
Steam, a naturally occurring substance, can be used for many things. We have learned how to utilize the energy in steam for our own benefit, and in this lesson, you'll learn about what exactly steam is and where it comes from.
