---|---|---|---|---|
Atomic mass - atomic number = number of neutrons
Describe how you find the number of neutrons that an atom has.
|
absorbs, increases
As the temperature rises from 25C to 60C, the material ___________ (absorbs/releases) heat and its kinetic energy (increases/decreases).
|
electromagnetic does not require a medium and mechanical does
What is the difference between electromagnetic and mechanical waves?
|
how fast an object moves, S=distance/time
What is speed and what is the formula?
|
coil
When you _________ the wire in an electromagnet, the magnetic field strengthens.
|
periods, groups
Rows on the periodic table are called ____________, while columns are called ____________.
|
density
A brick is cut into small pieces. Which physical property did not change when the brick was cut?
|
transverse
A wave that transfers energy that is perpendicular to its medium is called a ___________ wave
|
the tendency of objects to resist a change in motion, the larger the mass the more inertia than an object with a smaller mass
What is inertia, and how does it relate to mass?
|
closer, stronger
The __________ (further/closer) the electromagnet is to a paper clip, the __________(stronger/weaker) the attraction.
|
number of valence electrons
What do group numbers on the periodic table identify?
|
Physical: melting point, density, boiling point, shape
Chemical: reactivity, combustibility, formation of a precipitate
Split the following properties up into physical or chemical: melting point, reactivity, density, combustibility, boiling point, formation of a precipitate, shape
|
amplitude
the larger the amp. the louder the sound the smaller the amp. the softer the sound
What determines how loud or soft a sound wave is?
|
first law of motion
An object at rest remains at rest. An object in motions remains in motion unless acted upon an outside force. This describes which one of newtons laws?
|
series
In which of the types of circuits does electricity have only one path to follow?
|
elements, similar
The periodic table is organized into vertical groups of __________ (elements/compounds) that have __________ (different/similar) properties
|
mass, volume
If you are measuring an object in grams (g), what are you measuring?
If you are measuring an object in liters (L), what are you measuring? |
longitudinal
A wave where particles vibrate back and forth along the path that the wave moves is called a __________ wave.
|
velocity
An object increasing in acceleration is also increasing in what?
|
If the distance between two objects increases, the gravitational force between the objects will decrease
A student claims that the gravitational force between two objects depends upon the mass of the objects and the distance between them. Which arguments best supports the student’s claim?
|
one
How many valence electrons do the most reactive elements have?
|
D = mass/volume
What is the formula for finding the density of an object?
|
the frequency of a wave
the higher the frequency the higher the pitch the lower the frequency the lower the pitch
What determines how high or low the pitch of a wave will be?
|
final velocity-starting velocity/time
How do you find the average acceleration?
|
Electric forces take place when two charged objects are in motion
What is the difference between a magnetic force and an electric force?
