A-A* (AO3/4) - Simple Harmonic Motion

Test yourself on A-A* (AO3/4) - Simple Harmonic Motion

• What would happen to a pendulum clock without an 'escapement' to keep the pendulum swinging?

• Suppose you move from one city to another where the acceleration due to gravity is slightly greater. Taking your pendulum clock with you, what would you need to change so that the watch is correct?

• Which frequency of oscillation is required for a watch's second hand?

• The quartz tuning fork can be modelled as a cantilever (a beam fixed at one end). What would increase the frequency of oscillation?
