Energy Forms and
Transformations
Objective: Examine the various
forms of energy in order to
identify and describe specific
energy transformations.
DIRECTIONS: Use the
information contained on the
following slides to complete your
“Energy Concept Web”. Advance
to the next slide by clicking your
mouse or by pressing the “down
arrow” key one time.
Energy
• the “stuff” that makes
“stuff do stuff”
OR
• the ability to do work.
(W=F x D)
(F=force d=distance)
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!
Forms of energy
•Mechanical
•Heat/Thermal
•Chemical
•Electromagnetic
•Nuclear
•Electrical
Mechanical Energy
• Energy of motion
or position
• Moving school
bus, frog leaping,
sound, wind,
waterfall,
compressed spring
• Can be KE or PE
Link
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!
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
Electromagnetic Energy
• energy that travels in
waves; have electrical
and magnetic properties
• Light, Magnetism, XRays, Radio waves,
microwaves, ultraviolet
and infrared radiation
• KE
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
Electrical Energy
• Moving electrical
charges.
• Electricity
• from batteries,
power lines,
lightning, static
shock
• KE
