1. Energy Forms and Transformations
Objective: Examine the various forms of energy in order to identify and describe specific energy transformations.

2. Energy the “stuff” that makes “stuff do stuff” OR
the ability to do work. (W=F x D)
(F=force d=distance)

3. Types (kinds) of Energy
KE (kinetic energy)
PE (potential energy)
There are 2 different TYPES of energy,
but there are 6 FORMS of Energy.
Let’s see how each of these forms are different!

4. Forms of energy Mechanical Heat/Thermal Chemical Electromagnetic
Nuclear
Electrical

5. Mechanical Energy Energy of motion or position
Moving school bus, frog leaping, sound, wind, waterfall, compressed spring
Can be KE or PE

6. Heat/Thermal Energy
The internal motion of an objects atoms and molecules.
Measured by temperature.
The faster particles move, the more thermal energy they have.
KE only
When energy changes from one form to another, a small amount of thermal energy is always released!

7. Chemical Energy Energy stored by chemical bonds in an object.
When bonds are broken energy is released.
PE only
Match, gasoline, food, coal, wood, cells in your body

8. Electromagnetic Energy
energy that travels in waves; have electrical and magnetic properties
Light, Magnetism, X-Rays, Radio waves, microwaves, ultraviolet and infrared radiation KE

9. Nuclear Energy Energy stored in center (nucleus) of an atom
When an atom’s nucleus split apart (fission) this energy is released
Fusion (forming) when several nuclei join
The sun
Most powerful
PE only

10. Electrical Energy Moving electrical charges. Electricity
from batteries, power lines, lightning, static shock KE
