Abstract
Historical conceptions of projectile motion have varied from the Aristotelean through impetus theory to Newtonian mechanics; but its standard mathematical treatment is only possible within the Newtonian framework. This paper reports a study suggesting that many Australian Year 12 mathematics students do not conceptualise projectile motion within that framework, but rather use a variety of Aristotelean, impetus and Newtonian conceptions. The implications for the teaching of projectile motion are briefly discussed.
