  1. 1. quantities that cannot be measured by any mean or media.
  2. 4. a quantity that describes the net distance and direction of motion. It is always a vector quantity and is represented graphically by a vector arrow whose tall is at the starting point of motion and whose tip is at the ending point.
  3. 7. the rate of displacement of a system.
  4. 9. the rate of change of the velocity or speed of a system during time interval.
  5. 10. Motion in space which incorporates all the X, Y, and Z axis
  6. 11. the science of describing how things move.
  7. 14. an imaginary line that contains an origin as a zero point of position reference and is marked off in distance units.
  8. 15. a positive scalar quantity that is the total linear dimension traveled by a moving object during a time interval.
  9. 16. the rate of motion of a system.
  10. 17. relating to any property that has significance in three-dimensions, such as length, width, and height.
  11. 19. a measurable quantity that requires two pieces of information to fully describe it, magnitude and direction.

  1. 2. an imaginary line around which a system rotates or orbits, the center of rotational motion
  2. 3. any measurable quantity that can be completely described by a single piece of information
  3. 5. the location within a reference frame from which an observer measures all positions and motions
  4. 6. are an early worker in science who might have studied all aspects of the physical world.
  5. 8. the scientific study of forces and motions which consists of kinematics, dynamic, and statics.
  6. 12. any unbroken sequence of values in which the difference between adjacent values is nearly indistinguishable but the ends or limits of the sequence are greatly different.
  7. 13. the geometric space containing the point of reference and coordinate axes from which person observes or measures position and movement.
  8. 16. is a distinct part of the universe from elementary particles to galaxies that we may want to study or measure; it is separated from its surroundings by an actual or imaginary boundary.
  9. 18. two motions, one along the horizontal axis and the other along the vertical.
