A-LevelPhysicsOscillationsOct/Nov 2020Paper 4 Q310 Marks
A simple pendulum consists of a metal sphere suspended from a fixed point by means of a thread, as illustrated in [Figure 3.1]. The sphere of mass 94.0 g is displaced to one side through a horizontal distance of 12.7 cm. The centre of gravity of the sphere rises vertically by 0.90 cm. The sphere is released so that it oscillates. The sphere may be assumed to oscillate with simple harmonic motion.
