1D55.31 - Forces on Uniform Circular Motion with Lazy Susan and Flags


Lazy Susan and Flags Setup
Lazy Susan and Flags Setup



Code: 1D55.31


Demo Title: Forces on Uniform Circular Motion with Lazy Susan and Flags


Subject: Centrifugal Escape


Description:
A turntable is rotated until an object slides off. Try the object at a different radius and the same rotation speed. To demonstrate angular momentum, once the Lazy Susan is spun, the outer flags will experience more momentum compared to the inner flags, therefore causing the outer flags to fall out, and the inner flags to stay in place.


Procedure:

  • Explain demonstration.
  • Rotate the platform slowly and explain circular motion.
  • Use flag while table is still to move in straight line.
  • Rotating the table again explain how the flags have different forces depending on position further from the center.
  • Begin spinning the table faster until the force over comes the frictional force and the flags fall off the table.
  • Explain why the flag in the center does not move.
