Does the weight of an object affect its rate of fall?
Yes, the weight of an object affect its rate of fall. The stone will be faster because the crumpled piece of paper has very less mass so the gravitational force between the crumpled piece of paper and the earth will be also less on the other hand the stone has big mass as compared to the crumpled piece of paper so the gravitational force between the stone and the earth becomes very large i.e. the stone will be faster than crumpled piece of paper.
