Forms of Energy
![Page 4: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/4.jpg)
Energy is the ability to do work or to cause
change.
![Page 5: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/5.jpg)
Energy Transformation is: The change of
energy from one form to another.
Now what does this mean?
![Page 6: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/6.jpg)
The law states: Energy cannot be created nor
destroyed.
What does this mean? It means that energy can only
change its form from one type to another. The energy
of the world is a constant because the total amount
of the energy does not change.
For example: Let’s look at a flashlight. It runs on
batteries. The battery has chemical energy. When
the flashlight is turned on, the chemical energy is
first transformed into electrical energy and then into
light energy.
![Page 7: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/7.jpg)
Energy STORED in matter because of its
CHEMICAL bonds. It is released during a
chemical reaction (change).
Examples:
Battery
Digestion
Burning Wood/Fuel
![Page 8: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/8.jpg)
Energy in the form of electricity. Energy
from flowing electrons (negatively charged
particles).
Examples:
To light a bulb
Turn a motor
Run a hairdryer
![Page 9: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/9.jpg)
• Type of energy from the sun. Energy carried
by ELECTROMAGNETIC RADIATION.
• Radiant=LIGHT
• Examples:
– Visible Light/Sunlight (What you see)
– X-Rays (invisible)
– Microwaves (invisible)
– UV Light (invisible)
![Page 10: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/10.jpg)
Energy that an object (such as a machine)
has because of its movement or position. Or
you can say that energy of matter caused by
its POSITION or MOTION.
Examples:
Moving Cars
Wind
Waterfalls
Running
Sound
![Page 11: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/11.jpg)
The energy of heat, which transfers from
hotter objects to colder objects. Energy
comes from the motion of atoms and
molecules. The faster the particles in an
object move, the more thermal energy is
produced.
Examples:
Heating food
Drying clothes
Heat from a hairdryer
![Page 12: Forms of energy 2017](https://reader031.vdocuments.us/reader031/viewer/2022022415/5a64c3487f8b9ac21c8b58bd/html5/thumbnails/12.jpg)
Energy that is released when the nuclei of atoms
are split (fission)or combined (fusion).
Huh? Ok, think of it like this: When two cars
crash, it makes a lot of noise and parts flying
everywhere. When you “smash” two atoms
together, there are parts of the atom flying off
as well as energy.
Example: Nuclear Power Plant

When both the half page and the foldable
are glued in, get a energy graphic organizer
from the front
You may work in partners to fill this out. It
must be done by the end of the period and
glued into your journal on the next page.
