A bunch of feathers and a stone of the same mass fall at different rate in air.Which falls faster and why?How will your observation change if they are allowed to fall in the same vaccum?

Solution

Case I: Stone falls at faster rate -- Reason: Air resistance is less on stone due to less cross-sectional area

Case II: Both falls at the same rate -- Reason: No air resistance because of vacuum
