1. Mechanical, Electromagnetic, Electrical,
TYPES OF ENERGY
Mechanical, Electromagnetic, Electrical,
Chemical and Thermal

2. What is Mechanical Energy?
Energy due to a object’s motion (kinetic) or position (potential).
The bowling ball has mechanical energy.
When the ball strikes the pins, mechanical energy is transferred to the pins!

3. Mechanical = Potential + Kinetic
Mechanical energy is total energy an object has (when building up energy or when using it.)
The building up energy is potential. The using up is kinetic. When you have a high number of one, you have to have a low number of the other.

4. Examples of Mechanical Energy

5. What is Electromagnetic Energy?
Light energy
Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands

6. What is Electrical Energy?
Energy caused by the movement of electrons
Easily transported through power lines and converted into other forms of energy

7. What is Chemical Energy?
Energy that is available for release from chemical reactions.
The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.

8. Nuclear Energy
Nuclear Fusion
Nuclear Fusion
The energy of radiation and heat are released when the nuclei of atoms become so close at high speeds that they collide and form a new nucleus.

9. Nuclear Energy
Nuclear Fission
Nuclear Fission
The energy of radiation and heat are released when the nucleus of an atom decays and becomes the nuclei of other atoms.

10. Examples of Chemical Energy

11. What is Thermal Energy? Heat energy
The heat energy of an object determines how active its atoms are.
A “hot” object is one whose atoms and molecules are excited and show rapid movement.
A “cold” object's molecules and atoms will show less movement.

12. What types of energy are shown below?
Mechanical and Thermal Energy
(Don’t forget friction)

13. What type of energy is shown below?
Chemical Energy

14. What types of energy are shown below?
Electrical, Mechanical and
Electromagnetic Energy

15. Other Types of Energy Fossil Fuels (non-renewable)
Hydroelectric - changing water movement into electricity
Solar energy – using a photovoltaic to transform solar energy into electric energy.
Geothermal – using hot steam from areas where underground water is heated by hot rocks.
Wind – Using the motion of wind (kinetic energy) to change into electricity.

16. What type of energy is shown below?
Chemical Energy (ripening)

17. What type of energy is shown below?
Thermal Energy

18. Law of Conservation of Energy
- You can’t create emery
- You can’t destroy energy
- ENERGY CAN ONLY
CHANGE FORM.
Cool Fact: The energy the universe began with is the same amount of energy that exists today and in the future. It just constantly changes form!

19. Energy Tranformation
How does a car change energies? 5 DIFFERENT TIMES!

21. THERMAL ENERGY
Because of friction, no matter how energy transfers, some of the energy must be used to overcome the heat of friction. So you always have thermal energy.
There are 3 ways that you can transfer thermal energy:
Conduction
Convection and
Radiation

22. Conduction
What is it?
What doe it look like?
Conduction is when heat is transferred through touch. This is how solids transfer heat.

23. Convection What is it? What doe it look like?
Convection is when fluids (gases or liquids) transferred by mixing the fast-moving particles with slower-moving particles. Boiling water and the air/heating system in your house are examples.

24. Radiation
What doe it look like?
Radiation is the transfer of heat through empty space. Think about the sun’s rays, or standing in front of a fire.
