Energy
Mechanical
Thermal
Sound
Light
Chemical Energy
• Comes from bonds
between atoms in
molecules
• Chemical change =
energy released
• Examples:
• Gasoline burning in
a car
• Food we eat
Electrical Energy
• Flow of
electrons
(currents)
Mechanical Energy
• Energies of
motion
Nuclear Energy
• Comes from
reactions
between atomic
nuclei.
• Fission splits
• Fusion combines
• HUGE amounts
of energy
Radiant Energy
• Flows through
empty space
• Examples:
• Sunlight
• Radio waves
• X-rays
Sound Energy
• Vibration of
molecules in
surrounding
medium (usually
air)
Thermal Energy
• Heat energy from
fast moving
particles.
Law of Conservation
of Energy
• The law of conservation of
energy states that energy may
neither be created nor
destroyed.
Question 1
• What are some ways
humans us radiation, light,
and thermal energy to
improve our quality of life?
Electrical
Circuits
Objective:
• Today you will be able to
build a complete simple
electrical circuit and will
identify conductors and
insulators of electrical
energy.
Where does electricity
come from?
Electricity:
• The energy
of moving
charges in
atoms
(electrons).
Electrical Circuit:
• Any complete
path along
which electrons
can flow (from
negative to
positive).
Conductors:
• A material
that
carries
electrons
easily.
Insulator:
•
A material
that does
not carry
electrons,
such as
rubber,
plastic, and
glass.
