Purpose
To determine the relationship between air resistance force and velocity. By gathering data of a falling coffee filters and graph the data we collect, we will find a relationship of Fresistance = Kv^n.
Procedure
As professor drops coffee filters with different mass, we collect data to see how velocity changes.
Data
mass of coffee filters
By plotting dots of each 1/15s of flame, we can find a path of coffee filters in very short amount of times.
Graphs of the plotted dots of each 1/15s of flame.

Results/Analysis
Velocity and weight of each coffee filters
And the values of K and n from the linear fit of velocity vs weight graph
picture below is the linear fit graph
Conclusions
In this lab, we learned how to model a free fall object with an air resistance. We have concluded that Fresistance = 0.0006883 * V^1.366 and proved that there is an relationship between air resistance and velocity. We also measured our uncertainty due to errors of the experiment.
