Energy is the ability to do work.
(Work is a applying a force to move or change something. Therefore, something that has energy can apply force).

What is the Law of Conservation of Energy?

# data[].attributes.body
The law of conservation of energy is a law (obviously) that states that energy cannot be created or destroyed but may be changed from one form to another.
That means energy cannot disappear and it can't appear out of nowhere.

All types of energy have either Kinetic and Potential energy.
Kinetic energy: Energy in motion. When something is moving, it has kinetic energy.
Potential energy: Energy being stored. The energy is not being used right now, but it will be used soon.

Mechanical energy is the energy found when an object is in motion or its position. The mechanical energy can be both potential and kinetic energy and it uses energy to move, lift and hold objects. An example of mechanical energy is a bicycle. A bicycle uses mechanical energy to move.

Light energy (AKA Radiant Energy) is energy carried by light. Light energy contains electromagnetic radiation that is visible to the human eye and all types of electromagnetic radiation had light energy. An example  of light energy is a lightbulb. We can see that it is giving off visible light and that is light energy.

Thermal energy is energy produced when particles in an atom vibrate fast, and the temperature goes up. The hotter the temperature in an object, the more thermal heat that an object has. The amount of the thermal energy in a substance varies between the temperature and the amount of matter in an object. An example of thermal energy is a hot bowl of soup. The bowl of soup has a lot of thermal energy in it. That’s what makes it hot.

Sound energy is energy that is carried by sound waves which are created when an object vibrates. The soundwaves are able to travel threw matter. An example of sound energy are speakers on a TV. When you feel the speaker, you can feel the vibrations that it gives off to make sound energy.

Electrical energy (AKA Electricity) is energy carried by charged electron particles that move from place to place on a path called a circuit. An example of electrical energy is a computer. It uses electricity as energy.

Chemical energy is the energy stored inside of the bonds that hold together the atoms in matter.

Chemical energy not only is used to keep the atoms bonded together, it is also used in food and fuel.

An example of chemical energy is a person digesting food. The chemical energy is helping the person digest the food and giving the person energy.

1) Can energy change?
A- Yes, energy can change. One type of energy is able to turn into other types of energy. For example, if lightning strikes a tree (electrical) it will make the wood atoms vibrate faster and cause fire (thermal energy). This is a great example of changing energy because the electrical energy does not disappear, it just changes into thermal energy.
2) Can energy be created or destroyed?
A- No energy CANNOT be created or destroyed. According to the law of conservation of Energy, energy cannot be created or destroyed. Energy can however change forms and transfer energy into other things.

3) Can a object transfer more than one type of energy?
A- Yes, a object can transfer energy to another object. Think of it this way. When you get struck by lightning (or even get electrocuted) electrical energy from the lightning bolt into your body and causes you to have the electrical energy (as well as pain and suffering).
4) How does energy flow in a system?
A- In the picture below you will see a example of a science project my teacher had me do. In this project we can see that the little girl is using energy to make the water boil. The energy in this system transforms into different types of energy and makes the energy flow. The energy starts off as chemical then becomes mechanical, electrical and then thermal. That is how the energy flows threw the system.
