the total distance traveled divided by the total time taken to travel that distance.
|
less than
if an object sinks in a fluid, the buoyant force is _____the weight of the object
|
What is Thermal Energy
the total potential and and kinetic energy of an object
|
What is the electron dot diagram
this model represents valance electrons in an atom as dots around the element's chemical symbol
|
What is amplitude
for any wave, the larger this is, the more energy the wave carries
|
What is a straight horizontal line
this indicates constant velocity in a speed-time graph
|

|
What is volume
As the space in a container gets smaller, this decreases
|
what is a subscript
this shows the # of atoms of each element in the compound
|
What is standing
This type of wave occurs on a guitar because both ends are fixed

What is Density or 0.4 g/cm 3
a piece of unknown material has a mass of 3.0 g and a volume of 8.0 cm 3. If we divide the mass by the volume, it will give us this
|
What is viscosity
the measurement of a liquid's resistance to flow
|
What is a molecule
this is a group of atoms held together by covalent bonding that acts as an independent unit
|
What is interference
This occurs when waves that overlap combine to form a new wave
