Question 3 WAEC_MODEL_QUESTIONS_VOL1 • 2021 • PHYSICS • practical

A simple pendulum is used to determine the acceleration due to gravity. The length of the pendulum is measured as 0.500 m (±0.001 m). Using a stopwatch, the time for 20 complete oscillations is recorded as 40.2 s (±0.2 s).

Question Parts

( a )
Calculate the period of one oscillation and its percentage uncertainty.
( b )
Determine g and its percentage uncertainty using the pendulum formula \(T = 2π√(L/g)\).
( c )
State two possible sources of error in this experiment and suggest one method to minimise each.
