04-Sept-2014 Air resistance lab

The purpose of this experiment is to determine the relationship between the force of air resistance and speed of a falling object.

For the setup we used a lap top, camera, meter stick, coffee filters, and the second story balcony of building 13. The camera and laptop were positioned above ground level at a point equadiastant from the release point and the landing point. 

For the first round a single filter was dropped and recorded on video. Then two were stacked on each other and dropped. We continued this until the fifth round where a stack of five were dropped. In doing this we can determine the terminal velocity of the coffee filters.

The data was collected using the video function of LoggerPro to follow the position of the filters vs the time.

From the position vs time graphs the terminal velocity can be acquired for each of the drops. This is where the graph no longer curves and seems to remain constant. Then we use velocity, v the equation:
        F(of resistance) = kv^n
        k = 0.008542
        n = 1.794
        m(of 1 filter) = 1.035 g
