Question

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

Answer

When a bunch of feathers and a stone of same mass are allowed to fall in air, the stone falls faster than the bunch of feathers.

The reason is that upthrust due to air on stone is less than that on the bunch of feathers because the volume of stone is less than that of the bunch of feathers of same mass.

If they both are released simultaneously in vacuum, they will fall together because there will be no upthrust.
