Locating the Center of Gravity: The Dance of Normal and Frictional Forces
Balta, Nuri
Physics Teacher, v50 n8 p456-457 Nov 2012
Teaching physics concepts with the basic materials that are around us is one of the beauties of physics. Without expensive lab materials and long experiments, many physics concepts can be taught to students using simple tools. Demonstrations with these tools can be presented as discrepant events that surprise, amaze, or puzzle students. Greenslade has excellently described 14 things we can do with a stick, one of which is the "stick on two fingers." In this paper I describe some variations of the "stick on two fingers" demonstration. (Contains 6 figures.)
