Which type of energy is most often transported through metal wires?
Electrical and heat energy.
100
Why do you think the potential energy of a car parked on a hill is not completely changed into kinetic energy when the car rolls down the hill.
Some energy is converted to heat energy from he friction from the tires and the road.
100
What is the original source of the energy stored in coal, oil, and natural gas.
Fossil fuel is the original source
100
A resource that is replaced through natural cycles, such as solar, wind, and hydroelectric power.
What is Renewable Energy?
100
Which of the following forms of energy requires a medium through which to travel? A- Sound B- Visible lights C- X-rays D- Ultra violet light
A- Sound
200
Name three types of solar energy.
Ultra-violet radiation, inferred radiation, visible light.
200
When a candlewick burns, the flame heats the air, and the wax softens and melts. Explain how a burning candle demonstrates two ways the heat energy flows.
A candle demonstrates conduction because the heat energy softens wax. It also demonstrates convection when the warm air rises from the flame.
200
Which type of renewable energy is the less dependent on geography of an area?
Solar Energy
200
Energy that comes from the sun; includes light.
What is Solar Energy?
200
A purple object absorbs all colors of light except for A- Blue B-Green C-Orange D-Pruple
D- Purple
300
Name one energy transformation taking place on a wind turbine farm.
Wind energy to electrical energy.
300
When you speak, you produce wave energy. Name the energy and the medium through which this energy moves.
When you speak sound energy is produced; the medium is air.
300
Energy that is emitted in the form of wave or particles.
What is Radiation?
300
The vibrations that cause hearing and can travel through a variety of media.
What is Sound Energy?
300
When you go outside on a sunny day, you might feel heat from the sun on your skin. What type of Solar Energy is this? A- Gamma radiation B- Infrared radiation C- Ultra Violet radiation D- Visible light
B- Infrared radiation
400
Describe three energy transformations that occur when a car engine burns gasoline.
Chemical energy in gasoline, which is converted to mechanical energy. Also heat energy goes through the exhaust pipe.
400
Explain why you see a purple shirt as being purple.
It absorbs all colors except purple.

C- geothermal to electrical
500
A feather and a bowling ball dropped on the moon from the same height would hit the ground at the same time. Which object would have more kinetic energy?
The bowling ball has more kinetic energy because it has more mass.
500
Name two energy transformations accruing in a closed circuit.
Electrical and heat energy.
500
The change of direction of a wave caused by a change in speed as it passes from one medium into another.
What is Refraction?
500
The form of energy arising from motion of all the particles in a system; heat energy moves between things that are at different temperatures also called thermal energy.
What is Heat Energy?

Which of the following statements is not true about energy transformations? A-The place where the pole vaulter has the least potential energy at the top of his vault B- As a pole vaulter plants the pole, part of the vaulters kinetic energy is released in the form of heat. C- The force of gravity is one cause of the changes in the pole vaulters potential energy. D- AS the pole vaulter falls after he soars above the bar, he is gaining kinetic energy.
A-The place where the pole vaulter has the least potential energy at the top of his vault
