100
Of all the types of energy, which are often transported through metal wire?
What is 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? (hint- remember that no energy transformation is 100% efficient.)
What is Some of the energy is also converted into thermal (heat) energy from friction between the tires on the road?
100
Energy stored in bonds between atoms in molecules. When the bonds are made or broken, energy is released.
What is chemical energy?
100
Energy that comes from the sun
What is solar energy?
100
Occurs when light travels at different speeds throught different substances
What is refraction?
200
Name three types of solar energy.
What is ultraviolet radiation, infrared radiation, and visible light.
200
When a candle wick burns, the flame heats the air, and the wax softens and melts. Discuss how a candle demonstrates two ways that heat energy flows.
What is A candle demonstrates conduction. When two particles of the same wax meets the hot particles of the flame it melts into wax. A candle also demonstrates convection when heat is given off from the flame and the heat rises?
200
Produced when electrons flow through material or jumps from one place to another
What is electrical energy?
200
Vibrations that move through solids, liquids, and gases
What is sound energy?
200
The capture of light energy by a substance, when the light is neither reflected nor refracted
What is absorption?
300
Name one energy transformation taking place in the picture on page 119.
What is wind energy to electrical energy or solar into wind?
300
When you speak you produce wave energy. Name the energy and the medium through which this energy moves.
What is when a person speaks, that energy is sound energy and the medium is air?
300
Average kinetic energy of particles
What is heat energy?
300
Heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material
What is conduction?
300
A system of electrical parts that provides a path for an electrical current
What is circuit?
400
Describe three energy transformations that occur when a car engine burns gasoline.
What is Chemical energy in the gas converts to mechanical energy to make the car move and the thermal energy that is produced threw the exhaust pipe?
400
Write a sentence explaining why you see a purple shirt as purple.
What is a purple shirt absorbs all colors of light except purple which is why we see the color purple.
400
Consists of kinetic and potential energy
What is mechanical energy?
400
Heat energy transfers through the movement of a substance
What is convection?
400
A repeating vibration that travels through space and time
What is a wave?
500
Kinetic energy is the energy of an object in motion. A feather and a bowling ball are dropped on the moon from the same height would hit the ground at the same time. Which object would have more kinetic energy? Explain.
What is the bowling ball would have more kinetic energy because it has more mass?
500
Name two types of energy transformation occuring on the picture on page 125.
What is the angle of refraction is the same, 22 degrees.
500
Energy within the nucleus of an atom
What is nuclear energy?
500
Heat energy transfers when electromagnetic waves (visible light) interacts with particles increasing their kinetic energy
What is radiation?
500
The physical law stating the energy cannot be created nor destroyed
What is conservation of energy?
