1. Work: Definition, Characteristics, and Examples
Pushing a wall all day may feel like work, but unless you get that wall moving you're not doing any work according to the rules of physics. In this video lesson, you'll learn how work is defined as well as how to calculate the amount of work done on an object.
2. Work Done by a Variable Force
Doing work on an object is a simple concept: we apply a certain force over a certain distance. But in real life, that force is rarely constant. Therefore, we need to understand variable forces and be able to calculate them accurately.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. Pulleys: Basic Mechanics
Like other simple machines, pulleys can help us lift and move heavy loads with less effort. In this video lesson, you'll learn how pulleys do this as well as how this is possible while still obeying the law of conservation of energy.
10. Conservation of Mechanical Energy
Energy comes in many forms and for any system can never be created or destroyed. This holds true for mechanical energy, which also obeys this law of conservation of energy. In this video lesson, you'll explore how mechanical energy is converted or transferred between forms and objects.
11. Power: Definition and Mathematics
Work involves moving an object with a force, but power tells us how quickly that work is done. In this lesson, you will learn about how power depends on both work and time as well as see examples of how to calculate power.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
