Energy Unit Test Review PacketDirections: There are 7 stations that you will need to rotate between in order to review all concepts covered on the Energy Unit Test. Your teacher will direct you to move when it is time. Until the announcement, read the directions and work diligently at the station you are seated at.
STATION 1: Potential & Kinetic Energy
Fill in the blanks with the words “potential” or “kinetic” for questions 1-5. Then, fill in the blank with the appropriate word using your notes and your knowledge of physical science.
1. Energy at rest is known as ____________________ energy.
2. Energy in motion is known as __________________________ energy.
3. The higher an object moves above the ground, the more ________________________ energy it has.
4. The closer a moving object is to the ground, the more ___________________________ energy it has.
5. The greater the mass, the greater the ____________________ and ______________________ energy.
6. The downward force pulling on all objects is known as __________________________.
7. Look at the image of the roller coaster below. For each numbered section of the roller coaster identify if potential energy is high or low. Then, repeat for kinetic energy.
1. PE = ________ KE = ________2. PE = ________ KE = ________3. PE = ________ KE = ________4. PE = ________ KE = ________5. PE = ________ KE = ________6. PE = ________ KE = ________
STATION 2: Forms of Energy & Energy Transformations

Identify the energy transformations shown in each diagram.
1.
2.
3.
***To produce a noise from the turbine or generator, which type of energy must be present? _______________________
4. The _________________________ energy stored in a battery can be converted into ______________________ energy in series and parallel circuits, as seen in the image to the right.
5. You buy a one-time use handwarmer from CVS. The handwarmer works to warm your hands because __________________ energy is converted into ___________________ energy.
STATION 3: Heat EnergyFill in the blanks by choosing one of the two words written in the parenthesis.
_________________________ energy in the rotating
tires.
____________________ energy from the
fuel.
A Battery___________
___________
___________
1. As kinetic energy increases, the temperature of the substance being heated will ______________________ (increase/decrease). This is an example of a _________________ (direct/indirect) relationship.
2. The more mass in an object heated, the ______________ (more/less) thermal energy present. This is because the amount of thermal energy depends on how many molecules are moving around, as well as the speed at which they are moving.
3. Heat will always transfer from a __________________ (cold/hot) to __________________ (cold/hot) object.
4. Heat transfer through empty space is known as _____________________ (conduction/radiation).
5. Heat energy that can transfer through empty space is known as _________________ (ultra-violet/infrared) energy on the electromagnetic spectrum.
6. Heat transfer through direct contact is known as ______________________ (convection/conduction)
7. Heat transfer through the movement of air rising and sinking is known as _______________________ (convection/radiation)
8. During the rising and sinking of air, it is the _________________ (cold/warm) air that rises, and the __________________ (cold/warm) air that is sinking. This is due to density differences.
9. The direct source of heat energy for our Earth comes from the _____________________ (sun/moon).
10. Burning fossil fuels breaks the bonds, which releases ____________________ (thermal/chemical) energy. This energy is then used to boil of water in the furnace to produce steam. It takes _____________________ (thermal/electrical) energy to phase change liquid water into steam (water vapor).
STATION 4: Light Energy
Refer to the electromagnetic spectrum provided to answer the following questions.
1. The electromagnetic spectrum shown above is different from the one you previously used in class because it organizes the waves in order of _________________ (low/high) frequency to _______________ (low/high) frequency.
2. When a wave has a high frequency, it has a ________________ (short/long) wavelength.
3. The color of visible light that has the shortest wavelength is _______________.
4. The color of visible light that has the most energy is ___________________.
5. Which type of electromagnetic energy has the highest overall frequency on the chart? ________________________
6. Which type of electromagnetic energy is used to take pictures of bones? ____________
7. Draw a high frequency wave and a low frequency wave, making sure to show the difference in their wavelengths.
8. When an object appears green, that is because the object ______________________ (reflects/absorbs) green light.
9. Label the amplitude, crest, trough, and wavelength on the following transverse wave.
10. Label each figure with the appropriate key term below.
STATION 5: Sound Energy
High Frequency Low Frequency
A. B. C. D. E.
Fill in the blanks. Choose one of the words written in the parenthesis if the option is given.
1. Sound waves can be classified as _____________________ (mechanical, electromagnetic) waves.
2. Electromagnetic waves are able to travel through _______________________ (medium/empty space), unlike sound waves that require a ____________________ (medium/empty space) to travel.
3. Sound moves through a substance by ___________________ (vibrating/static).
4. Sound energy will travel most slowly through a ___________________ (solid/liquid/gas) because the particles are farthest apart. This requires each particle to move more in order to hit the next molecule and send the wave on.
5. A sound wave is an example of a ____________________ (longitudinal/transverse) wave. This is also called a ________________________ (extensional/compressional) wave.
6. In order for a sound wave to travel, molecules must ___________________ (touch/be spread far apart) from each other).
7. The speed of light is ________________________ (slower/faster) than the speed of sound. That is why you see ______________________ (lightening/thunder) before you hear ______________________ (lightening/thunder).
8. In a thunder storm, you have light (electromagnetic) and sound energy. Identify 2 other forms of energy that would also be present.
________________________ ________________________
STATION 6: Renewable & Nonrenewable Energy ResourcesClassify each of the following sources of energy as renewable or nonrenewable. If time permits, define each term.
Solar Oil Natural Gas Hydroelectric Biomass Geothermal Wind Nuclear Coal
1.Renewable Energy Sources Nonrenewable Energy Sources
2. Which type of energy contains the fossil fuels? __________________________________STATION 7: Electrical Energy & Magnetism
Fill in the blanks. Choose one of the two words written in the parenthesis if the option is given.
1. _____________________ (like/opposite) charges repel, while ______________________ (like/opposite) charges attract.
2. Electricity is energy that is generated from the movement of ____________________ (protons/electrons) through a(n) __________________ (empty space/wire).
3. Electricity is generated mostly in the United States through the burning of ____________________ ______________________ (fossil fuels/renewable resources).
4. In your house, you shouldn’t have any live, or exposed, wires. Wires tend to be wrapped in rubber or plastic material because these are ______________________ (conductors/insulators), rather than the metal wire, which is a _________________________ (conductor/insulator).
5. We would consider metals to have a ______________ (low/high) electrical conductivity.
6. Consider the circuit shown in Figure A.a. It can be identified as a
___________________ (series/parallel) circuit.
b. If the first light bulb is removed from the circuit, what will happen? ______________________________________
c. Why? ___________________________________________________________________________
d. Why does the switch need to be turned on in order for the electricity to travel? (See Figure B for further clarification of what is occurring in Figure A above.)
