100
Energy due to motion.
What is kinetic energy
100
These spread in waves from its source to create sound.
What is vibrations?
100
Light is a form of energy that travels in this way.
What is waves?
100
Thermal energy gives off this sensation.
What is heat?
100
This transfer of heat happens when two objects are in contact.
What is conduction?
200
Energy that is not causing any changes now, but could cause changes later.
What is potential energy.
200
Strings on a guitar that are more tightly stretch produce this type of pitch.
What is a higher pitch?
200
Light is a form of this type of radiation.
What is electromagnetic radiation?
200
When any form of matter gets warmer, the kinetic energy makes the object's molecules do this.
What is increase in speed?
200
This transfer of heat occurs through electromagnetic waves.
What is radiation?
300
By rubbing your hands together, kinetic energy turns into this form of energy.
What is thermal energy?
300
This is how you measure a sound's loudness.
What is decibels?
300
Light can travel in these three ways.
What is reflected, absorbed, and pass through.
300
When solids melt into liquid, or liquids evaporate into gas, this type of change has occurred.
What is a phase change?
300
This transfer of heat occurs when heat moves through a liquid or gas.
What is convection?
400
When fuel is burned in a car, furnace, or power plant, this type of energy occurs.
What is chemical energy?
400
The distance between crests is called this.
What is a wavelength?
400
A prism can do this to light.
What is refract?
400
This is the measure of thermal energy.
What is temperature?
400
When an egg is cooking in a hot frying pan, this transfer of heat is occurring.
What is conduction?
500
This type of energy holds protons together in the nucleus until the protons are knocked out of the nucleus.
What is nuclear energy?
500
These three things can occur when sound reaches a border between different materials.
What is reflect (or bounce back), absorb, and pass through?
500
An object can form a shadow when this happens.
What is blocking the path of light?
500
Thermal energy is the total of these two forms of energy in an an object.
What is kinetic and potential energy?
500
When the sun's rays enter a car's glass windows which makes the inside of a car warm, this transfer of heat is occurring.
What is radiation?
