Proportionals and mean proportional have been extensively used by Galileo in the analysis of uniformly accelerated motion. Mean proportionals are of special interest in uniformly accelerated motion because they are directly related to relative times of motion. It is, therefore, very important for us to get a clear understanding of the concept and its use in order to follow Galileo’s analysis. We discuss in this article, the concept, the definition, geometric representation and use of mean proportional. We also give two examples, one each, for motion on inclined plane and for projectile motion, that give a feel for the pivotal role played by mean proportional in Galileo’s analysis of uniformly accelerated motion.
