A simple pendulum is set up using a thin string and a small spherical bob. The length of the pendulum is measured with a metre rule and recorded as 1.00 m (to the nearest millimetre). Using a stop‑watch, the time for 20 complete oscillations is measured in five separate trials. The recorded times are: 40.2 s, 39.8 s, 40.0 s, 40.1 s and 39.9 s. Using the data provided, answer the following:

Question Parts

( a )

Calculate the average period of the pendulum (in seconds).

( b )

Using the average period obtained in (a), calculate the acceleration due to gravity g (in m s⁻²) for the pendulum. Give your answer to two decimal places.

( c )

State two possible sources of error that could affect the value of g obtained above.

( d )

Suggest two ways to minimise the errors identified in part (c).
