Transcript Forms of Energy

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)
Forms of energy
•Mechanical
•Heat/Thermal
•Chemical
•Electrical
•Electromagnetic
•Nuclear
Mechanical Energy
• Energy of motion
or position
• Sound, wind,
waterfall,
compressed spring
• KE or PE
• Not 100%
efficient much lost
to heat
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
Chemical Energy
• Energy stored by
chemical bonds in an
object.
• When bonds are broken
energy is released.
• PE only
• gasoline, food, coal,
wood
Electrical Energy
• Moving electrical
charges.
• Electricity
• from batteries,
power lines,
lightning
• KE
Radiant Energy
• energy that travels in
waves; have electrical
and magnetic properties
• Light, Magnetism, XRays, Radio waves,
microwaves,
ultraviolent and infrared
radiation
• KE
Nuclear Energy
• Energy stored in
center(nucleus) of an
atom
• Fission (breaking
apart)
• Fusion (forming)
• The sun
• Most powerful
• PE only
