In his work on weights (mechanics), Jordanus 'proved most helpful' in the medieval revision of Aristotle's theory of force and movement, in which he stated 'that a body can move only under one type of force at a time [since] if two were acting, one would destroy the other.' (Kline, p. 212) Jordanus 'showed that the force under which a body thrown straight out moved at any instant could be resolved into two components, natural gravity acting downward and a "violent" horizontal force of projection. This idea was taken up by da Vinci, Stevin, Galileo, and Descartes.' (ib … [Click Below for Full Description]
