WHAT IS KINETIC AND POTENTIAL ENERGY?
SCALE
(4) Highly Proficient ** (3) Proficient
I can make an argument for using one
energy source over another to produce
electrical energy using data and research
I have collected.
I can generate several examples or design
an experiment that shows energy is
transferred.
I can design and complete an experiment
to explain thermal energy transfers.
I can identify the ways that electrical
energy is generated using nonrenewable
and renewable resources. Explain the
pros and cons to the various sources.
I can identify, explain and compare the
ways that energy is transferred.

Essential Question: What are energy transformations? What is kinetic and potential energy?
ENERGY
Turbine Generators spin to cause copper wire and magnets to create electricity.
Water, wind and steam are what spin a turbine.
Turbine – A machine with blades that spin
Answer the 3
questions in
your
notebook.
LAW OF CONSERVATION OF ENERGY
Energy can be neither created nor destroyed.
Energy can only be transformed from one form to another
Energy is constant
Law of ThermodynamicsTotal amount of energy in the universe is constant. Energy can be neither created nor destroyed, but it can be changed from
one form to another
ENERGY
The ability to do work or create change
Energy can be potential (stored) or kineticPotential (stored) energy: energy that is
stored in some way
Kinetic energy: energy of motion, involves movement of some kind
POTENTIAL ENERGIES
Write the definition (Hint: it is underlined)
Write 1 example
GRAVITATIONAL ENERGY
Energy an object has due to place or position, such as its height above the Earth; a form of potential energy
Rock on the edge of a cliff, water behind a dam.
CHEMICAL ENERGY
Energy stored in the chemical bonds between atoms and molecules
Energy plants store by photosynthesis, any food we eat, coal, oil
NUCLEAR ENERGY
Energy stored in the nucleus of an atom; the energy that holds an atom together; sometimes called atomic energy
Uranium in a nuclear power plant and plutonium in a bomb

MECHANICAL (MOTION) ENERGY
The energy of an object or substance in movement; sometimes just called kinetic energy
Person dancing, car in motion, a thrown ball, flowing water.
ELECTRIC ENERGY
The energy of electrons moving or flowing within a substance
Power lines or home wiring, electricity from a battery
LIGHT ENERGY
Electromagnetic energy that travels in waves; also called radiant energy
Sunlight, the light of a lamp or of a TV, or computer monitor
THERMAL (HEAT) ENERGY
The internal energy of a substance due to random vibration and movement of its atoms and molecules; also called thermalenergy.
Heat from the burner of a stove, charcoal grill, forest fire.
SOUND ENERGY
Energy that moves through substances by compression waves; sound
Any kind of sound from humans, machines, animals, Ipods

ENERGY TRANSFORMATIONS
Review:
Energy can be neither created nor destroyed, but it can be transformed.
Light bulbs convert electric energy to light energy
Movement of our bodies converts chemical energy to kinetic energy
School bell converts electric energy to sound energy
Coal to electricity to light
Natural gas to heat to stove
