How Does Temperature Affect The Drag Of A Coffee Filter
Introduction:
It is often taught that if we drop two objects of varying masses simultaneously under the same conditions, they will reach the ground at the same time. However, this is rarely seen in the natural world. This discrepancy is attributed to a frictional force called drag. In a previous experiment, multiple variables thought to affect drag were tested. Previously tested variables were weight and surface area. It was found that weight had an inverse exponential effect on time it took the coffee filter to fall to the ground, while surface area had an inverse linear effect.
After multiple iterations of this experiment, two observations were points of discussion. While height was kept constant during each iteration, it was noticed that …show more content…
It is hypothesized that height has no affect on drag. The time it takes for the coffee filter is linearly related to the height at which the filter is dropped. Concavity, weight, and surface area was kept constant throughout the experiment.
Method:
The materials required for this experiment are a tape measure, two coffee filters, and a timer. Stack the coffee filters. The purpose of this is so that the system is more weighted. Measure the following heights to drop the coffee filters from: 1 ft, 2 ft, 3ft, 4ft, 5ft, and 6ft. Drop the coffee filters from the respective heights (Figure 1). Run multiple trials and calculate the average at each height. For the purpose of this experiment, two trials were performed at each height with the filter dropped concave down.
Results:
Figure 2 depicts the raw data results at their corresponding heights as well as the correlation coefficient. For obvious reasons, there is a high correlation between the height dropped and the time it took to fall to the ground. Surprisingly, the concavity in addition to the height did not add an additional variable to the relationship, despite being observed in other iterations of the
