Re: [Phys-l] Centrifugal redux

[Bernard Cleyet <bernardcleyet@redshift.com>]

That's why UCSC intro-Physics has a roundabout.  The shop made a  
wooden plate that fits on top.  Experiments are performed on the  
plate including rolling balls and swinging pendula in addition to  
standing on the running board.

bc had to convince the division to fund its move and a canvas  
roundabout port when the earthquake retrofit flying buttresses were  
built.

p.s. Here's a site to critique:

p.p.s. Is an unintended consequence of our overly litigious society a  
decreased experience of centrifugal force at a young age?
