Define and give the unit for
energy
A 100
Energy it the ability to do
work or cause change, and
is measured in Joules (J)
A 100
A decrease in either of
these factors will decrease
the kinetic energy of an
object
A 200
Mass or velocity
A 200
What is the difference
between Gravitational
Potential Energy and
Elastic Potential Energy.
How are they similar?
A 300
Both Gravitational and Elastic PE
are stored energys, that is they
are not currently being used.
GPE is stored in the height of an
object above the ground, and
EPE is stored in a stretch or
compression
A 300
At what point(s) in its swing does
the above object have its
maximum potential energy?
Explain.
A 400
Maximum Potential energy
is a point A, because that
is where the pendulum is
highest above the ground.
A 400
What energy conversions
are taking place at point D,
as the ball moves toward
A 500
The kinetic energy of the
pendulum is being
converted into potential
energy as the pendulum
gets higher.
A 500
Define chemical energy.
B 100
Chemical energy is energy
stored in the nucleus of an
atom.
B 100
How are mechanical
energy and kinetic
energy similar? How are
they different?
B 200
Both mechanical energy and
kinetic energy deal with the
energy of moving object, but
mechanical energy also includes
the potential energy of objects
due to their location.
B 200
A moving object usually converts
mechanical energy into what
form of energy? What causes the
conversion?
B 300
Moving objects usually
convert mechanical
energy into thermal
energy, as a result of
friction.
B 300
Describe the main
conversions which take place
when drops a basketball.
B 400
The gravitational potential energy
the basketball gained when it was
picked up is converted into kinetic
energy as it falls. When the ball hits
the ground, that kinetic energy is
converted into elastic potential
energy as the ball squishes, and then
converted back into kinetic and
gravitational PE.
B 400
How are temperature
and heat related?
B 500
Objects will transfer thermal
energy as heat, until they are
the same temperature.
Temperature differences drive
heat transfer.
B 500
Give three examples of
chemical energy
C 100
Matches, gasoline,
food, wood, candle
wax, leaves, etc
C 100
What forms of energy
are present in the
picture above?
C 200
Chemical (the food),
mechanical (the spinning
blade and the moving
person), electrical (the cord),
sound (the noise), thermal
(the blender motor gets hot)
C 200
What form(s) of energy could
be found in the picture
above?
C 300
Electromagnetic/light energy
(from screen), electrical
energy (cord from TV and to
gaming system), sound
energy (volume), mechanical
energy (guy pushing buttons
on controller), thermal energy
(TV gets hot)
C 300

C 400
Give 5 forms of energy present
in the diagram above.
C 400
Chemical (plants and fuel),
Sound (noise of engine),
Mechanical (moving plane),
Electrical (control panel),
Thermal (plane’s engine gets
hot), light (sun appears to be
shining)
C 400
What form(s) of energy
could you represent?
C 500
Chemical (food we eat and
how our body stores),
Mechanical (whenever we
move), Electrical (brain
impulses), Sound (talking),
Thermal (body heat)
C 500
Compare and contrast
thermal energy and
temperature when it comes
to the size of an object.
D 100
Since thermal energy is the
total energy of the particles in
an object, size does matter for
TE. The larger the object, the
greater the TE. Temperature,
being the average energy of the
particles, is not influenced by
the size of the object.
D 100
No more energy can be
removed from matter
at what temperature?
D 200
Absolute Zero (0 K, -273
°C, -460 °F)
D 200
The creation of wind at the
beach is best explained by
which method of heat
transfer?
D 300
Convection best explains
the creation of wind at
the beach, as warm air
rises and cooler air is
pushed down.
D 300
A thermometer, such as the
one above, depends on which
method of heat transfer?
D 400
A thermometer uses
conduction.
D 400
Describe how a
refrigerator can cool
food down.
D 500
Thermal energy from the
warmer food is transferred to
the cooler air in the fridge,
causing the food to get cooler,
and the air to get warmer.
D 500
What conversion takes
place when natural gas is
used to heat a pot of
water?
E 100
The chemical energy in the
natural gas is converted
into thermal energy.
E 100
When you rub your hands
together on a cold day,
what conversion is taking
place?
E 200
Mechanical Energy is
being converted into
thermal energy, through
friction.
E 200
The law of conservation of
energy says what about
energy?
E 300
Energy cannot be created
or destroyed.
E 300
Describe 3 energy conversions
which take place in the appliance
above.
E 400
Electrical energy is converted
into electromagnetic/light,
sound, and thermal energy.
Light and sound energy are
also converted into thermal
energy.
E 400
Describe conversions from 3
different sources which take
place in the above diagram.
E 500
Chemical energy is converted into
mechanical, electrical, and thermal
energy. Electrical energy is
converted into light and thermal
energy. Mechanical energy is
converted into thermal and sound
energy. Light energy is converted
into chemical energy. Nuclear
energy is converted into light
energy.
E 500
Fossil fuels, such as coal, are
examples of which form of energy?
F 100
Fossil fuels are examples of
chemical energy
F 100
When a fossil fuel is burned,
what happens to its chemical
energy?
F 200
The chemical energy is converted
into thermal energy, as well as
possibly light and sound energy.
F 200
What form of energy does a
spinning turbine have?
F 300
A spinning turbine has
mechanical energy.
F 300
Most power plants have the same basic
procedure to “create” electricity by
heating water. What are the general
steps to the procedure after the water
boils?
F 400
Steam rises, which turns a turbine.
The spinning turbine turns a
generator, which “creates” the
electricity.
F 400
Other than burning fossil fuels like
coal, name 3 other ways to create
steam for a power plant.
F 500
1) Burn biomass products
2) Use the nuclear energy of radioactive
materials, like uranium
3) Use the thermal energy of Earth
4) Use energy from the sun, focused with
mirrors
