Inspired by Archimedes and Benedetti, Galileo used hydrostatics as a model for his science. In his later work, Galileo abandoned the dynamical approach in favor of kinematics. After 1609, Galileo's kinematic treatment of an idealized model identified falling bodies as a case of uniformly accelerated motion and thereafter demonstrated it with his inclined plane experiment. D. Projectile Motion. Thus, if a body is indifferent to motion, no mover is required to sustain movement once a body is in motion.
Motion is now a state rather than a process, and rest is motion of zero speed in a continuum.
Galileo's conception of inertia as circular motion was an attempt to save Copernican circularity, particularly in the absence of any known force which could 'bend' rectilinear motion into an orbit. E. Galileo's Method. Galileo argued that theoretical conclusions required experimental verification even if the experimentation was mental rather than empirical. He was a thinker about nature and thought in terms of ideal situations rather than the complexities of the sensate world. Archimedean mathematics applied to physical problems rather than extensive experimental programs.
