Because the paper is much less dense than the textbook

When you drop a pen and a text book, they are larger objects and are not affected by air resistance. When you drop a pen and a sheet of paper, the paper is being strongly influenced by air resistance since it has a high surface area and small mass. In a vacuum with no air, both objects would fall at the same rate (9.8 m/s^2) and so would all other objects. Here is a video that explains this. http://www.youtube.com/watch?v=akWo3QpiL2I

Because a pen has more mass than the paper and the paper is affected by air resistance.

Because gravity makes the weight of everything drop to 0, and because a text book and a pen are not affected by air resistance because of their mass. But a sheet of paper has hardly any mass therefore it will be affected by air resistance. Yet if you ball up the sheet of paper it will not be affected by air resistance, reason I am actually not sure why.

Because the pen and text book are affected by gravitys weight. But the paper isnt affected by it so it drops down more slowly

The pen and the text book both have the same mass. But the paper is flat so it just floats down slowly and the pen drops faster than it.
