Coffee Filter Terminal Velocity.
Caudill, Wayne; Parker, Stone
In this presentation we will investigate the mathematics and physics of a free-falling object, not for the purpose of research to discover some profound physical phenomena, but rather to enhance students' ability to gather, organize, and analyze data using state of the art hand held technology. We will use the TI-83 plus (a sophisticated graphing calculator) and the TI-CBR (a Calculator Based sonic Ranging device) along with an adequate supply of 8 to 12 cup, no special brand, coffee filters. Since the coffee filters are not consumed, a single package is generally sufficient to supply the needs of more than one class. We will use the CBR and TI-83 Plus to collect data about the coffee filter drops. We will manually analyze some of the data and then use a previously written program to expedite the task. From the information obtained during the presentation we should be able to draw a reasonable conclusion about the terminal velocity that we challenge you to verify with your students. (Author)
