Steps
  1. Aristotle held that a force is needed to keep a body moving
  2. Galileo studied bodies rolling on inclined planes
  3. He extrapolated to the case with no friction at all
  4. That gave the law of inertia
  5. Newton restated it as his first law of motion
The chapter's own sequence, from the wrong view to the law. Source: syllabus Physics, Ch 4 Laws of Motion.
