#### Using a 33-45-78 Turntable to Show that Centripetal Acceleration is Proportional to the Square of the Velocity and Inversely Proportional to Radius

PocketLab in conjunction with a 33-45-78 RPM turntable is an ideal setup for studying centripetal acceleration. There are two videos that can be found in the Videos page of this web site. They show that (1) keeping radius constant implies that centripetal acceleration is proportional to the square of the velocity, (2) keeping velocity constant while varying the radius implies that centripetal acceleration is inversely proportional to the radius. The PocketLab is placed in its silicone...

#### PocketLab Experiment on Centripetal Acceleration with a 3-speed Ceiling Fan

There are two approaches that the teacher can take to doing this experiment on centripetal acceleration with a three-speed ceiling fan and PocketLab. The first choice is for those with an available three-speed ceiling fan. In this case students can collect all data by actually performing the experiment themselves. The PocketLab should be mounted to one of the ceiling fan blades with a very strong double stick mounting tape. For safety, however, students should still wear goggles. The author...
