  1. a the distance an object moves during a certain amount of time (miles per second; mph) Average speed = Distance divided by time
  2. b When all the forces act on an object that are balanced and the object doesn't move; no net force.
  3. c An object in motion will stay in motion unless a force acts on it. An object at rest will stay at rest unless a force acts on it.(No Net Force)
  4. d movement of objects, people, or animals in many different directions
