Scientists discovered in the middle of the nineteeth century that there is a way of defining certain quantities based upon location, velocity and configuration of matter and radiation, and "heat" content so that the total always stayed the same. Out of that came the law of conservation of energy. There are many types of energy and rules for calculating the amount of each type, but you don't need to know them all to appreciate the power of the method and the concept. The best I can do is refer you to other places to read, consitent with your grade level. You can do that kind of searching on your own. It is better if you come to use to ask more specific questions about what you do not understand.
Chapter 4 of The Feynman Lectures on Physics, Volume 1, is the best desription I have ever seen of what Energy is all about. It is aimed at college freshmen, but surprisingly readable. You probably will not find it online, but should be in most college and some high school libraries.
If you go to http://scholar.google.com and/or http://books.google.com, you might be able to find part or all of the resource online that DrWLS has given you. If it's still under copyright or if you have to "belong" to a certain group or school to access the information, though, you won't be able to read any of it.
Go to your local or college library. You're much more likely to find it in one of those places.
Of course, I can help explain the concept of energy to you! Energy is a fundamental concept in physics that describes the capacity of an object or system to do work or cause a change. It is all around us and is involved in nearly every aspect of our daily lives.
Now, if you want to understand the big idea of energy, it's important to start with the basic definition and then delve into its different forms and how it can be transferred between objects or transformed from one form to another. Here's a step-by-step breakdown on how to understand the concept of energy:
1. Definition of energy: Energy is defined as the ability to do work. Work is the transfer of energy that occurs when a force acts upon an object, causing it to move or change its state.
2. Forms of energy: Energy can exist in various forms. Some of the most common forms include kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), chemical energy (stored in chemical bonds), electrical energy (movement of electrons), and many more.
3. Conservation of energy: One of the most important principles related to energy is the conservation of energy. It states that energy cannot be created or destroyed, only converted from one form to another. This means that the total amount of energy in a closed system remains constant.
4. Energy transfer and transformation: Energy can be transferred from one object to another, or it can be transformed from one form to another. For example, when you turn on a light bulb, electrical energy is transformed into light and thermal energy.
5. Units of energy: Energy is measured in units called joules (J) in the International System of Units (SI). Other common units include calories (cal) and kilowatt-hours (kWh).
6. Practical applications: Energy plays a crucial role in various practical applications, such as generating electricity, powering vehicles, cooking food, and even in the human body for essential functions.
To deepen your understanding of energy, I recommend further reading or watching videos on the topic. There are many resources available online, including educational websites, scientific publications, and video platforms like YouTube, that provide explanations with examples and demonstrations.
By following these steps and exploring the different aspects of energy, you'll gradually gain a better understanding of this fundamental concept.
