Moving Fingers under a Stick: A Laboratory Activity
Massalha, Taha; Lanir, Yuval; Gluck, Paul
Physics Education, v46 n2 p211-214 Mar 2011
We consider a demonstration in which pupils alternately slide and stop their fingers under a long horizontal rod which they support. The changeover is described in terms of the relevant kinetic and static friction. We present a model calculation, performed on a spreadsheet, which clarifies the process and describes graphically the stepwise switches as the fingers approach the centre of mass of the rod. (Contains 6 figures.)
