Science Note: The sky hook - a centre of mass illusion
Issue 364 | Page 25 | Published Mar 2017
Description
In the UK, centre of mass experiments used to be plentiful and aimed at 12-13 year-old students. Currently, however, the topic of centre of mass and centre of weight seems to have shifted to an older age group (16-16 year-olds) to appear as a standard experiment on finding the centre of mass of an irregular-shaped card and a consideration of equilibrium, stability and toppling.
