The Weight of Iron and Feathers
Zendri, G.; Gratton, L. M.; Oss, S.
Physics Education, v49 n5 p544-548 Sep 2014
We discuss the popular question concerning the difference in weight between 1 kg of iron and 1 kg of feathers, by taking into account the non-trivial aspect of the semantic interpretation of "weight" and the weighting procedure. The inclusion of air buoyancy makes the correct answer an interesting one. We describe and comment on the experimental setup needed to obtain such an answer.
