Energy Unit Review
1. A material that does not
conduct heat well is called a(n)
Insulator
2. The total potential and kinetic
energy of the particles in an
object is called
Thermal energy
3. When generators are spun
by turbines, they
Produce electricity
4. Heat, like work, is an
energy transfer measured in
Joules
5. Heat is transferred from one
particle of matter to another
without the movement of matter
itself in a process called
Conduction
The total energy of all the
particles in a substance is called
Thermal energy
7. Kinetic energy increases as
Both mass and velocity
increase
8. Examples of kinetic energy
Something that moves
•A ball rolling down the street
9. The energy associated with
motion is called
Kinetic energy
10. The rate at which energy
is transferred is called
Power
11. The movement of thermal
energy from a warmer object to a
cooler object is called
heat
12. A change from one form of
energy into another
Energy transformation
13. When you rub your hands
together on a cold day, you use
friction to convert
Mechanical  thermal energy
14. The transfer of energy by
electromagnetic waves is called
Electromagnetic energy
15. Something that stores
chemical energy is
Food you eat
a match
a battery
16. Unlike kinetic energy,
potential energy is
Stored energy
17. Energy is measured in
units called
Joules
18. Any temperature on the
Kelvin scale can be changed to
Celsius by
Subtracting 273
19. A measure of the average
kinetic energy of the individual
particles in an object is called
Temperature
20. The law of conservation of
energy states that when one form
of energy is converted into
another
Energy is not created or
destroyed
21. A pole-vaulter first
converts kinetic energy into
Elastic potential energy
22. Visible light is an example
of
Electromagnetic energy
23. How would you calculate an
object’s mechanical energy?
ME = KE+PE
24. Absolute zero is shown as
0 on which scale?
The Kelvin scale
25. Water freezes at 32 degrees
on which temperature scale?
Fahrenheit
26. Moving water can be used
to produce electricity because
Most energy can be transformed
into other forms of energy
27. The ability to do work is
called
energy
28. Energy stored in the
nucleus of an atom is called
Nuclear energy
29. When fossil fuels are burned,
their chemical potential energy is
converted into
Thermal energy
30. What is the freezing point of
water in degrees Celsius?
What is the boiling point of water
in degrees Celsius?
Freezing point = 0 degrees
Boiling point = 100 degrees
31. Heated air moves from
baseboard heaters to the rest of
a room in a process called
Convection
32. The type of energy stored
by fossil fuels such as coal is
Chemical potential energy
33. Potential energy that
depends on height is called
Gravitational potential energy
34. No more energy can be
removed from matter at
0 Kelvin
35. What type of conversion is
taking place when natural gas is
used to heat water?
Chemical  Thermal
36. Niagara Falls is a good
example of
PE  KE
37. The energy associated with
the motion and position of an
object is
Mechanical energy
38. What type of energy does
a spinning turbine have?
Mechanical
39. Heat transfer occurs from
warm objects to colder ones
