Matter
What is matter?
Anything that has mass and takes up space.
What is energy?
The ability to do work or cause change.
What is a wave?
A disturbance that carries energy
What is an atom?
Basic unit of matter
Electricity is the movement of...
Electrons
How are the molecules in a solid different than those in a gas or a solid?
Solids are close together and rigid, liquids are farther apart and slide, and gas are even farther apart
What is the law of conservation of energy?
Matter can not be created nor destroyed only transformed
Longitudinal and Transverse
What atomic particle let's you identify the atomic number of an element?
Waves that require a medium are...
Mechanical waves
All phase changes are what type of change?
Physical change
1) This is energy in motion.
2) This is stored energy.
1) Kinetic
2) Potential
Amplitude controls this property of sound.
Volume
What is the difference between an element and a compound?
Elements = 1 type of atom
Compound = more than 1 type of atom
List 3 things that are not matter.

What is being added to a solid to turn it into a liquid?
Heat or Energy
List 3 categories of potential energy. (These are not things using it but big groupings)
Chemical, GPE, Elastic potential, nuclear
As an object approaches you, the pitch increases. This is due to what effect?
Doppler Effect
List 3 patterns in the periodic table.
Groups, periods, atomic number, atomic mass, reactivity, families
A physical change only changes this about an object.
It's appearance
A gas that turns directly into a solid is due to this state change.
Deposition
List 3 categories of Kinetic energy. (These are not things using it but big groupings)
Electric, thermal, sound, mechanical, electromagnetic (light)
Their frequency (wavelength)
