Light energy is a kind of kinetic energy that is projecting light that is visible to the human eye.

Example: A candle produces a type of kinetic energy that is light energy.

Energy is the ability to do work.

Example: When you eat nutritious food, they give you energy and give you the ability to do all sorts of work.

Work is the activity of doing something mentally or physically to achieve a certain goal.
Example: When you are running and dribbling a basketball, this is a form of work because your applying force to either change or move something.

What is the Law of Conservation of Energy?

# data[].attributes.body
The Law of Conservation of Energy states that energy cannot be created or destroyed.
Example: If you were to leave a ball on a floor, it wouldn't move because the Law of Conservation of Energy applies to this.

Chemical energy is the potential of a chemical substance to undergo a chemical reaction to transform into other substances.

Example: Batteries use chemical energy in order to power items.

# data[].attributes.body
Mechanical energy is the sum of kinetic energy and potential energy.

Example: When a windmill moves, in produces kinetic energy, when it is still it produces potential energy.

Electrical energy is energy that results to having a flow of electrical charge.

Example: when lightning appears, it is an act of electrical energy.

Thermal Energy is energy that has heat within it.

Example: The sun heats and warms our environment with thermal energy.

Can an object transfer more than one type of energy?

Can an object transfer more than one type of energy?

# data[].attributes.body
Yes, an object can transfer more than one type of energy. For example, a campfire produces light energy and thermal energy, which makes the campfire warm and bright. This shows how an object can transfer more than one type of energy because things like lightbulbs or campfires produce more than one type of energy.

Sound Energy is energy that is released by the vibration of objects.

Example: When you play the saxophone, sound energy vibrates throughout the instrument and through the hole.

# data[].attributes.body
No, energy cannot be created or destroyed. The law of conservation of energy states that energy cannot be created or destroyed. This law can be applied when you do chemical equation, any subscripts cannot be added or taken away.

Energy flows in a a system by energy being transferred into an objects energy that soon becomes that objects energy. In the picture below, there is a water faucet that produces mechanical energy, it then goes through the generator making electrical energy. When the electrical energy flows, it goes through the lightbulb creating both thermal and light energy.

# data[].attributes.body
Yes, things like batteries dying and fires running out of fuel are just energy changing, not getting destroyed. For example, when you switch on a lightbulb, it turns from electrical energy to thermal energy and light energy. Therefore, energy can change.
