How Short and Light Can a Simple Pendulum Be for Classroom Use?
Oliveira, V.
Physics Education, v49 n4 p387-389 Jul 2014
We compare the period of oscillation of an ideal simple pendulum with the period of a more "real" pendulum constituted of a rigid sphere and a rigid slender rod. We determine the relative error in the calculation of the local acceleration of gravity if the period of the ideal pendulum is used instead of the period of this real pendulum.
