Modelling mechanics in software

Image
Mechanics is more than just an application of algebra and geometry, it is the primary application of geometry and algebra.  Newton’s development of calculus was to answer problems in what we would now call mechanics and much of his work was geometrical in nature.  However, students study less geometry than they use to and this, along with difficulties in algebra, can result in issues when they start studying mechanics. As a remedy to this software that links geometry and algebra is perfect tool in which students can practise modelling situations in mechanics.  This can complement their studies in mechanics and enhance their skills. In particular two main methods that lend themselves well to being represented in software are interactive force diagrams and animations of position. Interactive force diagrams Interactive force diagrams can be created where the vectors for the forces acting on an object are represented dynamically. The diagram below shows the forces acting
