What is wrinkled paper called?
In geometry and topology, crumpling is the process whereby a sheet of paper or other two-dimensional manifold undergoes disordered deformation to yield a three-dimensional structure comprising a random network of ridges and facets with variable density.
What happened to the paper when it was crumpled?
When the paper is smooth, it exposes a large surface to the air beneath it which slows its descent. Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster.

Why is rolled paper stronger than flat paper?
Paper is very weak under compression and is somewhat stronger under tension (i.e., it collapses when you push the ends together but it doesn’t pull apart easily). By folding or rolling the paper, you create a “thickness” which allows the paper to reinforce itself and not collapse so easily.
Which will fall faster the stone or crumpled paper?
The force of gravity is the same on both objects, as they are dropped from the same height. Since drag is in essence just friction caused by air, it takes more energy to bring the paper down to the Earth comapared to the ball and so the ball has more energy being used/applied so it falls faster and in less time.
