ENERGY

By the end of this lesson, students will be able to give an example for each type of energy and understand the difference between potential and kinetic energy.

Today we will discuss the difference between kinetic and potential energy, and briefly give a description of each type of energy.

Question of the Day:
What is energy?

ANSWER-

Potential Energy
Potential Energy is something that has the potential to move, but isn't at this point in time.
Example: A pencil sitting on a desk

Kinetic Energy
Kinetic Energy is something that is moving currently.
Example: A roller coaster

Types of Energy
Mechanical
Electric
Chemical
Magnetic
Nuclear
Thermal
Gravitational
Sound
Elastic

Mechanical Energy
Mechanical Energy is simply energy involving physical movement.
Example: A ball rolling down a hill

Electric Energy
Electric Energy is movement of electrical charges. Basically, electricity is electrical energy.
Example: A lamp plugged into an outlet

Chemical Energy
Chemical Energy is energy stored in compounds. It is released any time that a chemical reaction occurs.
Example: A battery is an example of stored chemical energy

Magnetic Energy
Magnetic Energy is any kind of energy having to do with magnetism.
Example: Two magnets repelling each other

Nuclear Energy
Nuclear Energy is using nuclear reactions to create energy
Example: Fission, the splitting of atoms

Thermal Energy
Thermal Energy is also known as heat energy. It is any energy generated from heat.
Example: The sun

Gravitational Energy
Gravitational Energy is potential energy that is associated with gravity or gravitational force.
Example: a rock sitting atop a mountain

Sound Energy
Sound Energy is also known as acoustic energy. It deals with vibrations in matter.
Example: A buzzing bee

Elastic Energy
Elastic Energy is energy associated with an object twisting,curving, or being manipulated in some way. It usually involves tension as well
Example: A rubber band

Light Energy
Light Energy is energy that produces light.
Example: Flashlight

QUIZ

• What is potential energy?
• What is kinetic energy?
• Give an example of each type of energy (Mechanical, Electric, Chemcial,Magnetic,Nuclear,Thermal,Gravitational, Sound, Elastic, and Light).

Biblical Integration
God gave us many different kinds of energy for a reason: He wanted us to use each for a different purpose. I Peter 4:10 says, "Each of you should use whatever gift you have received to serve others, as faithful stewards of God's grace in its various forms." Just as we should use the gifts God gave us, we should also use our knowledge of energy to the best of our ability in order to fulfill the Creation Mandate.
