Coffee+Filter+Lab

In Your Notebook**:
 * COFFEE FILTER LAB

__Problem:__ Determine the model for drag for a coffee filter falling through air. (i.e., does Fdrag = bv or bv^2?)

__Lab Design__: You draw it!

__Measured Data__: Give a brief explanation of how you measured the terminal velocity.
 * **number of filters** || **mass** || **drag force** || **terminal velocity** ||

__Graphs__: Sketch the graph you made in LoggerPro of Fdrag vs. terminal velocity. Write the equation of the best-fit line/curve. This equation will help you determine the "b" value for the coffee filters ... this value is essential for writing your program.

__Computer Model__: This is where you analyze how well your computer model matches with your actual data. For completeness, you should tape a hard copy of your VPython program to the back of a white page (that way you'll have it for college). Have your program output the velocity of the coffee filter when it hits the ground after a drop of 5 meters. Make a table comparing the terminal velocities from the program to that of your data, for all 5 trials.

__Conclusion__: Based on your data and computer model, what is the model for the drag force? COMMENT!
