1. 6.2 Energy

2. What is energy?
Energy is the ability to do work or cause change.

3. Types of Energy
There are 2 types of energy:
Potential
Kinetic

4. Kinetic Energy
Energy of Motion (Movement)
Energy in use

5. Potential Energy Stored energy Not being used
Can be turned into Kinetic Energy

6. Example:

8. Identify the Type of Energy:

9. Forms of Energy There are many forms of energy: Mechanical (moving)
Chemical (released when chemicals react)
Found in food
Light (energy you see)
Electrical (electrical charge)

10. Cont. Thermal (energy that makes things feel warm)
Nuclear (in the nucleus of an atom)
Sound (energy you hear)
Electromagnetic (travels in waves in space- Examples: X-ray, radio, microwaves)
Solar (energy from the sun)

11. Identify the form:

12. Cont.

13. Energy Transformation
Energy can transform from one form to another.
Forms of energy can convert from one form to another:

14. Examples:

16. Energy cannot be created or destroyed What Happens to Energy?
Law of Conservation of Energy:
Energy cannot
be created
or destroyed

17. What does that mean? We Do Not make energy
We can not get rid of energy
Energy only changes form

18. Sources Of Energy We depend on Natural Resources to get our energy
Some are Renewable, some are Nonrenewable

19. Renewable Resource
Resources that can be replaced at the same rate they are used
Examples: Trees, Animals

20. Nonrenewable Resources
Form at a much slower rate than they are used
Examples: Coal, Natural Gas, Oil, Minerals

21. Energy Resources
Resources that are used to provide the energy we need.
Some are renewable, some are not
Each has its own advantages and disadvantages

22. Types of Energy Resources
Solar
Nuclear
Geothermal

23. Cont.
Fossil Fuels
Wind
Biomass

24. Review Name the two types of Energy and explain the difference
Name as many forms of energy as you can
Explain the transformation of energy using lunch as an example
What does the law of Conservation of Energy state?

25. Cont.
