Abstract

The treatment of pendulum motion in early 18th century Newtonian textbooks is quite different to what we find in today's physics textbooks and is based on presuppositions and mathematical techniques which are not widely used today. In spite of a desire to present Newton's new philosophy of nature as found in his Principia 18th century textbook analysis of pendulum motion appears to owe more to Galileo's insights than to those of Newton. The following case study outlines this analysis and identifies some of its distinctive features as a resource for teachers wishing to refer to this period in the history of science.
