Is There Air Resistance In Free Fall?

Free fall is when an object starts falling down without any initial acceleration. It starts in the rest position and gradually gains speed. This speed is cause by the gravity and its accumulation is interfered by the air resistance. If it was not for the air resistance, two such different objects as a stone and a feather would reach the floor gaining the same speed and over the same period of time.
