Timing the Swing
Hang a bob from the cord, measure the length from the point of suspension to the centre of the bob, and pull it aside to a small angle read on the front-plate scale, staying below about 10° so that T = 2π√(L/g) holds. Time many complete swings and divide, which shrinks the error of starting and stopping the watch. Repeating at several lengths and plotting T² against L gives a straight line through the origin with gradient 4π²/g.
Steel Bob or Aluminium Bob?
Swap the bobs, measure the length again to the new bob’s centre, and the period stays the same, showing that it does not depend on the mass of the bob. Being less dense than steel, an aluminium bob of similar size loses its swing sooner, because air resistance is larger compared with its weight, so the pair also serves for a damping comparison. The angular scale lets pupils check that the period hardly changes as the amplitude dies away.
