When dropped in a vacuum, where there is no air resistance, both a big coffee filter and a small coffee filter would fall at the same rate due to gravity. However, in a real-world scenario where air resistance is a factor, the larger coffee filter would typically experience more air resistance than the smaller one. This increased air resistance can slow down its fall compared to the smaller coffee filter.
As a result, in a normal environment, the small coffee filter would likely fall faster than the big coffee filter.
