... Newton’s First Law of Motion – Inertia – At Rest or Constant Velocity Aristotle (384 -322 B.C.) believed that the natural state of a body was at rest and a force was required to keep an objection in motion. Furthermore, the greater the force the greater the speed. Some 2000 years later Galileo found ...
