  1. 2. the rate at which an object's position changes, measured in meters per second
  2. 4. rate at which velocity changes with time, in terms of both speed and direction
  3. 5. a proposed explanation or educated guess
  4. 9. measures the length between objects or points without regard for direction
  5. 10. the force exerted on an object due to gravity
  6. 12. a quantity that has both magnitude and direction
  7. 13. the rate of change of position for a time interval which is very small (almost zero)
  8. 15. a place or object used for comparison to determine if something is in motion

  1. 1. the displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs
  2. 3. a set of coordinates that can be used to determine positions and velocities of objects in that frame
  3. 6. the change in an object's position, meaning the straight-line distance between its starting point and ending point, considering both magnitude and direction
  4. 7. the location of an object at any given time
  5. 8. the motion of an object where gravity is the only force acting upon it
  6. 11. quantity that designates how fast and in what direction a point is moving
  7. 14. the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change
