We first connected the Pasco 6540 Interface device to a motion sensor and placed the sensor on the floor. Protected the sensor by placing books that were thicker than the sensor on either side. With one person holding a set of 10 combined coffee filters over the sensor at a height of approximately 2m, we chose monitor and examined the position to ensure the filters were over the sensor. When the filter was in position we selected record and dropped the filter. Then again preformed step 2 with a 10g weight.
Terminal velocity occurs when the acceleration of a freely falling object is equal to zero.
Below we see the numerical results. Note that the coefficient of drag used here is from a secondary source that found the number experimentally and its accuracy is questioned. For purposes none other than thoroughness, we provide dimensions of the coffee filter below. The following is the collected data along with the constants and calculated variables used in finding the terminal velocity. Calculated Vt Exper.
