ENERGY AND SOUND STUDY GUIDE
1. Anything which gives you the ability to do work, cause motion, or cause a change to
occur is called ENERGY. (P. 5, Video: Exploring Energy)
2. When energy is used to push or pull on something then you are applying a(n) FORCE
to that object. (Video: Exploring Energy)
2.5 In the metric system the unit which is used to measure force is the NEWTON (nt).
3. If the object that you are applying a force to moves as a result of applying a force to it
then you are doing WORK . (Video: Exploring Energy)
4. The formula used to calculate the amount of work that you are doing is: (Video:
Exploring Energy)
Work (W) = FORCE (F) X DISTANCE (D)
5. The metric unit which is used to measure the amount of work being done is a(n)
NEWTON – METERS (nt – m) or a(n) JOULE (J) (Video: Exploring Energy)
5.5 If the object that you are applying a force to does not move as a result of applying that
force then you have NOT done any work. (Video: Exploring Energy)
6. Most of the sources of energy we use on the earth are a by-product of our SUN .
(Video: Exploring Energy)
7. The seven major classifications or types of energy which can be used to do work, cause
motion, or cause a change to occur are: (Video: Exploring Energy)
A. RADIANT or ELECTROMAGNETIC Energy
E. HEAT or THERMAL Energy
B. MECHANICAL Energy
F. ELECTRICAL Energy
C. CHEMICAL Energy
G. NUCLEAR Energy
D. SOUND Energy
8. An energy source which can’t be replaced after its been used is called a(n)
NON-RENEWABLE energy source. (Video: Exploring Energy)
Page 2
9. Some examples of energy sources which are non-renewable energy sources are:
(Video: Exploring Energy)
A. COAL
C. METHANE
E. URANIUM
B. PETROLEUM
D. PROPANE
10. Any energy source which can be replaced after its been used is called a(n) RENEWABLE
energy source. (Video: Exploring Energy)
11. Some examples of energy sources which are renewable energy sources are: (Video:
Exploring Energy)
A. BIOMASS
C. GEOTHERMAL
B. HYDROPOWER
D. SOLAR
E. WIND
12. Some problems associated with the overuse of fossil fuels is that they are
NON RENEWABLE energy sources, they cause GLOBAL WARMING due to the greenhouse
effect and they cause the production of _ACID RAIN and WATER AND AIR POLLUTANTS.
(Video: Exploring Energy)
13. All of the different types of energy which can be used to do work, cause motion, or
cause a change to occur can be POTENTIAL or KINETIC in form. (Video: Exploring Energy)
14. If an object or substance possesses energy that is at rest or stored up waiting to be
released to do work, cause motion, or cause a change to occur then it is POTENTIAL in
form. (Video: Exploring Energy)
15. Potential energy is sometimes called energy of REST or STORED energy.
(Video: Exploring Energy)
16. Some examples of objects or substances which would contain energy that is potential
in form are: (Video: Exploring Energy)
A. FOSSIL FUELS
D. GUN POWDER
B. BATTERY
E. STRETCHED GUM BAND
C. FOOD
F. ANY OB JECT RAISED ABOVE THE GROUND
PAGE 3
17. Any object or substance raised above the ground possesses a special type of potential
energy called GRAVITATIONAL potential energy. (Video: Exploring Energy)
18. If energy stored up in an object or substance is actually being released to do work,
cause motion, or cause a change to occur then it is KINETIC in form. (Video: Exploring
Energy)
19. Kinetic energy is sometimes called energy of MOTION , energy of ACTION , or
RELEASED energy. (Video: Exploring Energy)
20. Some examples of objects or substances which contain energy that is kinetic in form
are: (Video: Exploring Energy)
A. ALL MOVING OBJECTS
C. EXPLODING FIRECRACKER
B. BURNING FOSSIL FUELS
D. RELEASING A SET MOUSE TRAP
21. The Law of Conservation of ENERGY says that you can change from one energy form to
another but you can’t lose or gain energy during the process. (Video: Exploring Energy)
22. According to the Law of Conservation of Energy when you turn on a flashlight energy is
not being created (gained) or destroyed (lost) during the process only its form is being
changed from CHEMICAL energy, to ELECTRICAL energy, to RADIANT energy. (Video:
Exploring Energy)
23. A(n) ENERGY WAVE is a disturbance that occurs in nature in which energy is being
moved or transported from the source of the energy to another location. (P. 6, VCR:
Characteristics of Energy Waves)
24. The two major types of energy waves are: (P. 6 – 8, VCR: Characteristics of Energy
Waves)
A. LONGITUDINAL energy wave
B. TRANSVERSE energy wave
25. A form of energy which travels through the atoms or molecules of an object or
substance as a series of back and forth vibrations of kinetic energy is called SOUND .
(P. 34 – 35, VCR: Characteristics of Energy Waves, VCR: Sound)
26. The field of science which is involved with the study of the characteristics and
properties of sound is called ACOUSTICS .
