A bunch of feathers and a stone of the same mass are released simultaneously in air. Which will fall faster and why? How will you observation be different if they are released simultaneously in vacuum?

Due to many factors like the surface area of feathers is more than that of stone so the air friction acting on these materials will be more on the feather than that of stone so the stone will be attracted faster to the earth than the feathers
In vacuum there is no air friction acting on these materials.

The feathers fall much after the stone falls because of air friction. The observation will be different in vaccum as there is no friction in air because of absence of air. As a result of which the stone will fall at the same time without any delay.
