Oscillations
Perform 3 sets of measurements for each different oscillation, (you will get more marks if you do 2 sets of repeats).
Measure at least 30 periods in total.
Preferably make each measurement 20 periods long.
Precaution: minimise oscillations in any other plane other than the one being observed ("Careful release to avoid unwanted modes of oscillation"). Explain how you did this.
Always write times to two d.p., never to the nearest second.
Precaution: do small amplitude oscillations
Precaution: say that you did several periods at once to minimise reaction time errors.
Precaution: use a fiducial marker at the centre of the oscillation.
