  1. 1. The measure of the inertia of matter in an object or within the boundaries of a physical system.
  2. 4. The mass of a substance or object contained within a stated volumetric unit.
  3. 7. The space enclosed or occupied by an object or within the boundaries of a physical system. Scientists derive these units from the cube of units of length.
  4. 9. A convenient way to express very large or small numbers. We write the notation in the form M × 10n, where M is a number greater than or equal to 1 and less than 10, and n is a positive or negative integer.
  5. 11. An assessment of the random errors associated with a series of measurements. Results showing small random errors around an average value for a given measurement.

  1. 2. A digit in a measurement used to communicate the precision of the measurement. They are all the digits known from the instrument scale plus one estimated digit determined by the user.
  2. 3. A system of measurement in which all units of a given dimension are related to each other by powers of 10. The main system used today is the SI.
  3. 5. An assessment of the measurement is to its acceptable value. A smaller error means a more precise measurement.
  4. 6. An assessment of the exactness of a measurement. A more accurate measurement has more known digits than a less accurate measurement of the same quantity. The fineness of an instrument’s scale markings determines the maximum accuracy of a measurement.
  5. 8. The global scientific metric system. The abbreviation stands for the French name Systeme International d'Unites.
  6. 10. The measure of the earth’s gravity acting on the matter in an object. It is a force measured in newtons (N).
