Fig. 3.1 depicts a simple pendulum moving to and fro between P and Q. A full oscillation happens when the bob travels from P to Q and then returns to P.
(a(i))[2]
Using the readings in Fig. 3.2, work out the time for one complete oscillation of the pendulum.
(a(ii))[4]
The method in (a) does not give a sufficiently accurate value for one complete oscillation of the pendulum. Describe how the student could obtain an accurate value for one complete oscillation of the pendulum.
(b)[2]
State the kinetic energy of the pendulum bob at R and at Q.
