Matter
What are the three main states of matter?
Solids,liquids,and gasses
What is potential energy?
The energy an object has due to position
What does speed measure?
How fast an object is going
How are different types of radiation arranged along the electromagnetic spectrum?
By the amount of energy they carry
What does a magnetic field look like?
It's invisible.
How does the molecules in ice move
The molecules vibrate close together
What is kinetic energy?
The energy an object has due to motion
Which of the following can be used to measure an object's speed?
Miles per hour
What is the difference between a wave and a particle?
A particle is a discrete unit of energy; a wave is a continuous flow of energy
What can you infer about magnetic domains from the fact that they are arrangements of atoms?
The individual domains are extremely small.
What is matter
Anything that has mass and takes up space
When does a yo-yo have the most potential energy?
When it is at it's highest point
What does acceleration measure?
The rate which a speed travels
Which word best describes gamma rays?
Destructive
If you have an electromagnet, how can you make its magnetic field stronger?
Increase the strength of the electrical current
What do water vapor, liquid water, and ice have in common?
They all have the same chemical properties
When is potential energy transformed into kinetic energy?
When an object at rest is out in motion
What is the difference between positive and negative acceleration?
Positive acceleration means speed up but negative acceleration means slow down
What do all forms of electromagnetic radiation have in common?
Their speed
A flow of electrons through a conductor is called:
A current
What's the easiest way to add energy to matter?
Heat it up
What do potential and kinetic energy have in common?
They're both related to motion
If you're sitting still in a chair reading this, what is your acceleration?
0 m/s/s
What produces electromagnetic radiation?
Electrons changing energy levels
How are the magnetic domains of a magnet different from the domains of an ordinary piece of metal?
In a magnet, the domains all point in the same direction; in an ordinary piece of metal, they're all jumbled up.
