Energy Transfer: Examples & Overview

1. Energy Transfer: Examples & Overview

Learn about energy and how the sun provides the energy needed to sustain life on Earth. Discover energy transfer and how energy is neither created nor destroyed, but moves from one place to another or changes from one form to another.

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.

Energy and Life: The Transformation of Energy in Living Organisms

3. 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.

What is Energy Conservation? - Definition, Process & Examples

4. What is Energy Conservation? - Definition, Process & Examples

This lesson will explain what the conservation of energy principle is and why it matters, using some real-life examples of how it works in our day-to-day lives. A short quiz will follow.

Applying the First Law of Thermodynamics to Reactions & Processes

5. Applying the First Law of Thermodynamics to Reactions & Processes

In this lesson, we'll see how different forms of energy are related. We'll learn and apply the laws of conservation of mass and energy to chemical reactions, physical processes, nuclear reactions, and biological processes. A quiz will test your new knowledge.

Second Law of Thermodynamics: Entropy and Systems

6. 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.

The Third Law of Thermodynamics & Its Application to Absolute Entropy

7. The Third Law of Thermodynamics & Its Application to Absolute Entropy

After completing this lesson, you will be able to explain what the third law of thermodynamics is, and how that relates to the concept of absolute entropy. A short quiz will follow.
