Energy Notes
Energy: The work that energy allows us to do can be divided into 5 main tasks.
1.) Produce
light
4.) Produce
2.) Produce
heat
5.) Power technology
3.) Produce
motion
Motion (Kinetic) Energy:
growth
Types of Energy
 The energy that an object has because of its
motion.
 Examples:
o

Thermal energy- Hand warmers
Sound energy- Listening to music on stereo
Light energy- Projector in classroom
Motion energy- Kid doing push-ups
Stored (Potential) Energy:
 The energy an object has because of its
position
or because of the
arrangement of parts, rather than its motion.
 Examples:
o

Gravitational energy- Slinky
Chemical energy- Battery
Elastic energy- Rubber band
Nuclear energy- Nuclear power plant
Electrical energy- Christmas lights
Energy Transfers
Law of Conservation of energy:
When energy is transferred there is always an
energy receiver.
receiver always
energy source
The source always
and
decreases in energy and the
increases in energy.
Energy Diagrams
The transformation of energy can be shown using an Energy Diagram.
