Topic and Concept:

Location:

attachment:BlockonRotatingTable-01-400.jpg

Abstract:

A turntable is rotated until objects slide off or tip over.

 Equipment Location ID Number Turntable ME, Bay , Shelf # Blocks ME, Bay , Shelf #

Important Setup Notes:

• N/A

Setup and Procedure:

1. Place the turntable on the lecture bench such that the table is horizontally oriented.
2. Plug in the turntable making sure the power switch is in the "off" position.
3. Place block(s) on turn table.
4. Turn on the turntable by flipping the switch to the "on" position.

Cautions, Warnings, or Safety Concerns:

• N/A

Discussion:

When the turntable moves, the only force on the blocks allowing them to move with the turntable is friction. As per Newton's first law, the blocks, once set in motion, "want" to travel in a straight line. To alter their motion and put them into a circular trajectory, a centripetal force must act on the blocks.
