Energy
You may not know it, but energy is all around us. In fact you are made of energy. Energy is
defined as the ability to do work. In order to do any work you need energy. Electronics use
energy, cars use energy and even your body uses energy.
The Bulldozer uses energy to move the dirt.
1. What is energy?
Answer:
Types of Energy
Energy comes in two different types. One type of energy is called kinetic energy. Kinetic
energy is the energy of motion. It is the energy an object has due to its motion. For
example, a baseball that has been hit has kinetic energy because it is flying through the air.
The other type of energy is called potential energy. Potential energy is the energy an
object or system has because of its position in space or the arrangement of its particles.
Simply put, it is the energy that could be used to do work. For example, a rubber band that
has been stretched has potential energy because if you let it go it will snap back.

Answer:
Kinetic Energy
Forms of Energy
Energy comes in many different forms. All forms have the ability to do work. We are going
to learn about 6 forms of energy. However, there are other forms of energy that we will
not discuss here.
Chemical Energy
All matter is made of atoms. Atoms come in many different forms. Molecules are made of
different arrangements of these atoms. The atoms are held together by what are called
chemical bonds. Within these chemical bonds a lot of potential energy is stored. We call
this energy chemical energy. Chemical energy is the energy stored in chemical bonds.
When we break these chemical bonds in a chemical reaction this energy is released.

2. Give an example of how we use chemical energy in our lives.
Answer:
Heat Energy (Thermal Energy)
Heat energy is the movement of the atoms in matter. Heat is in everything. When an
object gains heat the atoms begin to move faster and as an object loses heat the atoms
slow down.
Burning wood turns the chemical energy into heat
energy.

lives?

2. Give an example of how we use heat energy in our lives.
Answer:
Mechanical Energy
The energy that an object has because of its movement or because of its position is called
mechanical energy. An example of mechanical energy is when you draw a bow and store
the energy until you let it go and the energy is transferred to the arrow causing it to fly
through the air.
Bows use mechanical energy.
Engines use mechanical energy.

Answer:
Nuclear Energy
Inside of all of the matter around you there is a very large of amount of potential energy.
This energy is stored in the nucleus of the atom. We call this nuclear energy. When this
energy is released it is called a nuclear reaction. This type of reaction can be very
dangerous if it is not controlled. Einstein was the first to calculate how much energy there
is in the nucleus of an atom. This is when he came up with his famous equation E = mc2.

Answer:
Radiant Energy (Light Energy)
Light itself is a form of energy. We call it radiant energy or electromagnetic energy.
Radiant energy is the energy in light. Some radiant energy we can see but not all radiant
energy is visible. In fact most radiant energy is invisible. There are many different types of
radiant energy. Radio waves, microwaves, infrared rays, visible light, ultraviolet rays, Xrays, and gamma rays. We call these the electromagnetic spectrum. Most of these forms of
radiant energy have so much energy that they are dangerous to humans.

Answer:
Electrical Energy (Electricity)
Not only is there energy stored in the nucleus of an atom, there is energy in the electrons
that spin around it. We call it electrical energy. Electrical energy is the energy that is
contained in the movement of electrons. This is where we get our electricity that we use to
power most of what we use in our homes.
