Forms of Energy
A. What is energy?
1. is the ability to cause change.
2. Energy can cause an object to its position or its motion.
B. Kinetic Energy—Energy of Motion
1. Energy due to motion is .
2. The faster an object moves, the kinetic energy it has.
3. The kinetic energy of an object depends on its as well
as its speed.
4. If two objects move at the same speed, the object with the
mass will have more kinetic energy.
C. Potential Energy—Stored Energy
1. is stored energy.
2. When you are holding a book energy is stored between the book and Earth;
this type of energy is called potential energy. This
type of potential energy stored between an object and Earth depends on the
and of the object.
3. Elastic potential energy is energy stored in objects that are compressed
or .
4. When you stretch a rubber band, you are storing
potential energy. When you let go of the rubber band, stored elastic potential
energy is transformed into energy.
5. Food has potential energy, which is the
energy stored in the bonds between atoms. This energy is released when
occur.
D. Energy and Work
1. is the transfer of energy that occurs when a force is
applied over a distance.
2. is sometimes described as the ability to do work.

E. Other Forms of Energy
1. Energy can be measured in units of .
2. is the total kinetic energy and potential energy in an
object or group of objects.
3. The energy carried by sound waves is . It is produced
by objects that .
4. All materials are made of atoms and molecules that are always
. The energy of atoms and molecules due to their
motion is .
5. is the energy carried by an electric current.
6. , such as microwaves, can travel through a vacuum.
7. The energy of electromagnetic waves is called .
8. is stored in the nucleus of an atom.
9. The Sun releases nuclear energy when the of atoms
join together.
10. Nuclear power plants release energy by nuclei.
