Wave
*for 50: name the two peaks of a wave*
The nature of a wave which allows it to travel at a direction perpendicular to oscillating fields.

No work is done on the crate.
*for 50: if the cable is cut, what force would do work on the crate?*
These waves require a medium to propagate, and cannot travel in a vacuum.
Mechanical Waves
*for 50: give an example of a mechanical wave*
At which medium would sound travel fastest?
Solids
*for 50 points: how about light?*
Energy in transit, which flows due to a difference in temperature.
Heat
*for 50: Name the three main types of heat transfer*
Between a bowling ball and a feather, which one would reach the ground first in a freefall?
Both at the same time.
*for 50 points: how would either reach the ground first in the same freefall?*
Described as the amount of work an object can do based on its motion.
Kinetic Energy
*for 50: what is the formula for KE?*
The length of time it would take for one full wave to pass through a given point.
Period
*for 50: what is the formula for period, given frequency?*
A phenomenon which is created when sound is continuously reflected inside a room, prolonging the existence of the sound.
Reverb(eration)
*for 50: what do you call a reflected sound?*
What temperature corresponds to the term "absolute zero"?
Zero Kelvin.
*for 50: What other scale has an "absolute zero"?*
If the mass of an object doubles (while force is kept constant), what happens to its acceleration?
It would be reduced by half.
*for 50: state the Law of Acceleration*

Order the colors of light from fastest to slowest in a vacuum.
They all move at the same speed in a vacuum.
*for 50: what is the approximate value for the speed of light?*
The amount of heat that must be added (or removed) to an object in order to change its temperature by one unit.
Specific Heat Capacity
