Energy Transformation

Types of Energy and Energy Tran

1. Energy Transformations
Ch 5.3
Physical Science
Mrs. Neistadt

2. Objectives:
•Be able to identify the six types of energy
•Be able to use the Law of Conservation of
Energy to show how energy transforms as
it is used, demonstrated with a flow chart.

3. What is energy?
•*Energy is the ability to do work
–Examples: moving ball, moving wind,
gasoline, electricity…
–Any object that has energy has the ability to
create a force
Examples: a moving ball, electricity, gasoline…

4. *Different Types of Energy:
1.Kinetic energy
2.Potential energy
3.Mechanical energy
4.Radiant energy
5.Electrical energy
6.Chemical energy
7.Nuclear energy
8.Thermal energy

5. Potential Energy
•*Potential Energy- Energy that is stored
and waiting to be used later
•*3 Types of Potential Energy
–Gravitational Potential Energy (rollercoaster)
–Chemical Potential Energy (battery)
–Elastic or Compression (rubberband or
spring)

6. Potential Energy:

7. Kinetic Energy
•*Kinetic Energy is the energy of motion.
–Anything that is moving is said to have kinetic
energy.
–We measure the amount of energy in joules.
–Increasing speed of motion or mass of the
object will increase the amount of Kinetic
Energy.

8. Kinetic Energy

9. Potential or Kinetic?

10. Conservation of Energy
•*Law of Conservation of Energy:
Energy can never be created or destroyed, just
transformed from one form into another
Example: Roller Coasters!!

11. Your turn…
•Refer to your handout:
5.3 Energy Transformations

12. *Mechanical Energy
•*Mechanical Energy is the energy
possessed by an object due to its motion
or its stored energy of position.
–It can be kinetic or potential
–*an object that has mechanical energy can do
work- like the Simple Machines from ch 4
–Example:

14. *Radiant Energy
•*Radiant Energy is also known as
electromagnetic energy.
•*Radiant Energy is light waves that we see
or feel as heat
–Example: Heat from a fire; heat from the sun.

16. *Electrical Energy
•*Electrical Energy- energy from electricity
–Electrical energy is often converted from other
forms, such as chemical energy (coal)
through a process to become electricity.
–*Examples: Electricity in our homes and
businesses

17. *Chemical Energy
•*Chemical Energy is the type of energy
stored in molecules.
–*Examples: Batteries; Food; Fossil Fuels

18. *Nuclear Energy
•*Nuclear Energy comes from splitting an
atom, or fusing two atoms together. When
an atom is split or fused, a huge amount of
energy is released.
–*Examples: This is how the sun and other
stars make energy
–*Nuclear Power Plants

19. *Thermal Energy
•*Thermal Energy is heat energy. Heat is the flow of
energy from a high temp to a lower temp.

20. *Energy Transformations:
Ch 5.3
•If energy doesn’t get destroyed? Where
does it go?
•Energy is never destroyed; it transforms
into one of the other types of energy.
–Example: Food is chemical potential energy,
that is used as kinetic energy when you run a
mile

21. What are the energy
transformations?

22. Your turn part II…
•Refer to your handout, page 2: Energy
Scenarios
•Create flow charts to go with each
scenario to show the energy
transformations that are occurring.
•Use a separate sheet of paper to create a
poster of an energy transformation:
demonstrate it with a flow chart and be
ready to share it with the class.
Be creative, but be accurate!
