Learning Outcomes

Candidates should be able to:

  • show understanding that all physical quantities consist of a numerical magnitude and a unit
  • recall the following base quantities and their units: mass (kg), length (m), time (s), current (A), temperature (K), amount of substance (mol)
  • use the following prefixes and their symbols to indicate decimal sub-multiples and multiples of the SI units: nano (n), micro (ยต), milli (m), centi (c), deci (d), kilo (k), mega (M), giga (G)
  • show an understanding of the orders of magnitude of the sizes of common objects ranging from a typical atom to the Earth
  • state what is meant by scalar and vector quantities and give common examples of each
  • add two vectors to determine a resultant by a graphical method
  • describe how to measure a variety of lengths with appropriate accuracy by means of tapes, rules, micrometers and calipers, using a vernier scale as necessary
  • describe how to measure a short interval of time including the period of a simple pendulum with appropriate accuracy using stopwatches or appropriate instruments
