The Moving Centre of Mass of a Leaking Bob
Arun, P.
European Journal of Physics, v31 n4 p811-818 Jul 2010
The evaluation of variation in the oscillation time period of a simple pendulum as its mass varies proves a rich source of discussion in a physics classroom, overcoming erroneous notions carried forward by students as to what constitutes the pendulum's length, by picking up only the results of approximations and ignoring the rigorous definition. The discussion also presents an exercise for evaluating the centre of mass of geometrical shapes and system of bodies. In all, the pedagogical value of the problem is worth both theoretical and experimental efforts. This paper discusses the theoretical considerations. (Contains 3 figures.)
