Demonstrations are cataloged according to PIRA Bibliography
PLEASE REQUEST DEMOS WELL IN ADVANCE
Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

You have selected the following Demos:
Purpose:To demonstrate aspects of acceleration in a rotating system and to show the directions of these accelerations.
Procedure:First, place accelerometer perpendicular to radius and slowly crank platform noting position of water in the accelerometer. Next, place the accelerometer along the radius and spin. Since the accelerometer is accelerated towards the center of the rotating platform, the water inside will feel a fictitious force pushing it towards the outer edge which can be seen by the change of water level as you look from the inner to the outer edges.
