One dimension - Freefall of a baseball and a piece of paper [video]
MetadataShow full item record
Here I hold a horizontal piece of paper and a baseball at the same height from the table. I then ask which will strike the table first, if they are simultaneously released from rest. After receiving their responses, I then crumple the paper into as compact spherical shape as possible, and the baseball and paper are then simultaneously released from rest at the same height. They strike the table at nearly the same time. This demonstration dramatically points out the dependence of air resistance upon geometry. In the next demonstration, the book and a sheet of paper are both held horizontally at the same height and are simultaneously released from rest. A magazine works well as an alternative to a book. I then ask the students which object will have the greater acceleration in each of three different cases. "Drafting," in which an object substantially reduces the air resistance on another object behind it (as employed in bicycle racing), does not fully account for the effect here. This is because the paper can overhang the book by a small amount, but the paper still accelerates the same as the book. There is apparently a suction effect that tends to maintain the paper in contact with the book.
