Re: [Phys-l] friction

["Folkerts, Timothy J" <FolkertsT@bartonccc.edu>]

How about an analysis of an actual curling throw!

If you know the distance from the throw to the target and can measure the time from a video, you should have plenty of info to find speeds, acceleration, force, and (most significantly) the coefficient of friction.

There must be a clip somewhere on the internet of curling, along with references about the length of the "field".

Isn't it important to know the temperatures of bothe 
the ice and the granite ... as well as the weight and 
surface area of the granite and the ice to 
determine their coefficient of friction??
