Learning Outcomes:

​Students 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 (µ), 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.
