A simple pendulum is used in several experiments.
The pendulum is 1 m in length and the bob (the mass located at the
lower end of the pendulum) weighs 1 kg. A very accurate clock is used
to time the period of motion of the pendulum. Firstly, the timing
is
carried out with the pendulum located at the South Pole. Subsequently
the pendulum is relocated to the equator and the timing of its motion is
repeated.
Answer each of the following:
i.
Calculate the angular velocity of the pendulum bob when
the
pendulum is located on the equator.
ii.
It is found that its period of oscillation is slightly different when
timed at the South Pole and when timed on the equator. Explain
why this is the case.
