what you can do to make the paper fall as fast as the book withot putting the paper under or inside the book.​

Sagot :

Answer:

Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster. When the sheet of paper is placed on the book, there is no air at all beneath it. For this reason, the two objects fall at the same speed. This force is called gravity.
