Unit 2 Frayer Models
Definition:
The energy of an object that is due to the
object’s motion.
Facts or characteristics:
Can be transferred from one moving object to
another.
Kinetic

Definition:
Substances or objects that do not conduct
thermal energy very well.
Examples:
A wooden tongue depressor.
Oven mitt
Facts or characteristics:
Thermal energy is transferred very slowly.
Thermal
Insulators
Definition:
The total energy of motion and position of an
object.
Examples:
A moving car
A book resting on a table

Definition:
Produced by the vibrations of electrically
charged particles.
Examples:
Ultraviolet light (unseen by human)
Flashlight
Non-examples:
Curling iron
Copper pipe
Facts or characteristics:
Energy that an object has due to its position
(potential energy) or due to its motion
(kinetic energy).
Mechanical
Energy
Non-examples:
Thermal energy
Sound energy
Atoms
Electron
Facts or characteristics:
Causes energy to be transmitted, but does not
need to be carried through matter
(vacuum)
Can be converted into other forms
of energy
Light Energy
Non-examples:
Dog barking
Definition:
Sound is the movement of energy through
substances in longitudinal
(compression/rarefaction) waves.
Facts or characteristics:
Produced when a force causes an object or
substance to vibrate; energy transferred
through the substance in a wave.
Sound Energy
Examples:
A vibrating drum
Non-examples:
Lightbulb
Definition:
Total amount of energy cannot be created or
destroyed, but can be changed from one form
to another.
Facts or characteristics:
Energy is conserved in all cases.
Law of
Conservation
of Energy
Examples:
When a moving car hits a parked car
and the parked car moves.
Non-examples:
Thoughts
Definition:
The transfer of thermal energy from one
substance to another through direct contact.
Facts or characteristics:
- One of the methods of thermal energy (heat)
transfer.
- Can occur within a substance.
Conduction
Examples:
Placing a metal pole directly in a
fire and the pole becomes hot.
the
Non-examples:
Placing a metal pole outside in
the sunlight.
Definition:
The transfer of thermal energy by the
movement of a liquid or a gas.
Facts or characteristics:
Another method in which thermal energy is
transferred.
Convection
Examples:
Boiling water in a pot (the water
moves in roughly circular patterns.
Non-examples:
Placing a metal pole directly in
fire and the pole becomes hot.
Definition:
The transfer of thermal energy by
electromagnetic waves, such as visible light
and infrared waves.
Examples:
Sun (emits visible light, and infrared
And ultraviolet waves)
Facts or characteristics:
- A third way in which thermal energy is
transferred.
- Unlike conduction or convection,
radiation can involve either an
energy transfer between particles
Radiation
of matter or an energy transfer
across empty space.
Non-examples:
Boiling water in a pot (the water
moves in roughly circular patterns.
Definition:
The energy transferred between objects that
are at different temperatures.
Examples:
A popsicle
Fresh cup of hot cocoa
Facts or characteristics:
Heat causes objects to feel hot or cold or to
get hot or cold under the right conditions.
Heat
Non-examples:
Absolute zero
Definition:
The energy of moving electrons.
Examples:
Electrical outlets
Facts or characteristics:
Electrons are negatively charged particles of
atoms.
Electrical
Energy
Definition:
The ability to do work.
Examples:
Light
Heat
Facts or characteristics:
Work is done when a force causes an object to
move in the direction of that force.
Energy
Definition:
A change from one form of energy to another
form of energy.
Examples:
Alarm clock (electrical energy to
light and sound energies
