Here's why:
* Air resistance: A feather experiences much more air resistance than a leaf. This is because it has a larger surface area relative to its weight. Air resistance slows the feather down, making it fall much slower.
* Shape and weight: While both have a large surface area, a leaf is usually denser and heavier than a feather. This difference in weight also influences how quickly they fall.
* In a vacuum: In a vacuum, where there's no air resistance, both a leaf and a feather would fall at the same rate due to gravity.
So, the short answer is: In normal conditions, a leaf falls faster than a feather because of air resistance. But, if we remove the air, they would fall at the same rate!
