What kind of energy does something have if it CAN move, but isn't moving right now?
kinetic energy
mechanical kinetic energy
gravity
mechanical potential energy
What direction does sound travel in?
All directions
Straight forward
Down
What is white light made of?
vibration
different wavelengths of energy making up the colors of the rainbow (ROY G BIV)
mechanical energy from the colors of the rainbow (ROY G BIV)
When we see a red piece of paper, what does that mean? What is happening to the light energy?
The red wavelength is absorbed. The other colors are reflected back to your eye.
All the light energy is reflected back to your eye. Nothing is absorbed.
The red wavelength is reflected back to your eye. All the other colors are absorbed.
What are the colors of the rainbow?
Red, orange, green, blue, violet
Red, orange, yellow, green, blue, violet
Red, orange, yellow, green, blue, indigo, violet
You put a pencil in a cup of water and it looks bent. Why?
Refraction causes the light to bend as it passes through the water.
Reflection causes the light to bend as it passes through the water.
Absorption causes the light to bend as it passes through the water.
You see your face in the mirror. Why?
Refraction bends the light rays hitting the mirror.
Absorption soaks up the light rays hitting the mirror.
Reflection bounces back the light rays hitting the mirror.
What kind of energy comes from a lamp besides light?
mechanical
electrical
heat
What causes sound energy?
electricity
vibration
volume
Can sound travel through a gas?
Yes.
No.
Can sound travel through a liquid?
Yes.
No.
Can sound travel through a solid?
Yes
No
What is a conductor?
Something that does not let electrical or heat energy pass through.
Something that stores energy.
Something that lets electrical or heat energy pass through easily.
What is an insulator?
Something that lets heat, or electrical energy pass through.
Something that does not let sound, heat, or electrical energy pass through.
Something that stores energy
What science tool do we use to measure heat energy?
barometer
thermometer
volumetric flask
What's the difference between kinetic and potential energy?
Potential energy is more powerful than kinetic energy.
Potential energy is another word for mechanical energy. Kinetic energy is stored energy.
Potential energy is stored energy (energy that is not being used right now). Kinetic energy is another word for mechanical energy. It's the energy of things in motion.
A flashlight works by changing one kind of energy into another kind of energy. What is the change that takes place?
Electrical to light.
Light.
Chemical to electrical to light and heat.
You use an iPod to listen to the Rock Cycle Blues. What energy changes are taking place here?
Electric to sound
Chemical to electric to sound
Electric to mechanical
What energy change is taking place when you clap your hands?
Mechanical to sound
Electric to sound
No change.
Which color absorbs more light energy: White or black?
Neither. They both absorb the same amount of light energy.
White
Black
What is the science word for heat energy?
thermometer
thermal energy
weather
What can white light be broken up into?
Different kinds of energy
a prism
Different wavelengths of energy, which show up as a rainbow (ROY G BIV).
What is the name used to remember the colors of the rainbow?
ROY G BIV
ROY B GIV
Albert Einstein
What's the difference between potential energy and kinetic energy?
Nothing. They mean the same thing.
Potential energy is stored energy; kinetic energy is moving energy.
Potential energy is moving energy; kinetic energy is stored energy.
What's the difference between kinetic energy and mechanical energy?
Nothing. They mean the same thing.
Kinetic energy is moving; mechanical energy is still.
Kinetic energy has more power.
What color will you see if a shirt absorbs all the wavelengths of light?
Black
White
Yellow
What color will you see if a sheet of paper reflects all the wavelengths of light?
black
white
It depends
What color will you see if a piece of paper absorbs all the wavelengths of light except blue?
