Faster than "g", Revisited with High-Speed Imaging
Vollmer, Michael; Mollmann, Klaus-Peter
European Journal of Physics, v33 n5 p1277-1288 Sep 2012
The introduction of modern high-speed cameras in physics teaching provides a tool not only for easy visualization, but also for quantitative analysis of many simple though fast occurring phenomena. As an example, we present a very well-known demonstration experiment--sometimes also discussed in the context of falling chimneys--which is commonly described as "faster than gravity", "faster than g", "free fall paradox" or simply "falling stick". So far, only a few experimental investigations have utilized photography with a maximum of 41 frames s[superscript -1]. In this work, high-speed imaging with 1000 fps was used to verify theoretical predictions for the classical experiment. In addition, a modified experiment was performed to better distinguish various theoretical outcomes and also visualize the underlying physics. The topic is well suited for student projects in undergraduate courses which combine experimental laboratory work with computer modelling. (Contains 11 figures.)
