Question 1 IGCSE_MODEL_QUESTIONS_VOL1 • 2018 • PHYSICS • practical

A student is investigating the relationship between the length of a simple pendulum and its period. The student uses a 50 cm long string, attaches a small metal bob, and measures the time for 20 complete oscillations with a digital stopwatch. The experiment is repeated for three different lengths: 40 cm, 60 cm and 80 cm. The recorded times for 20 oscillations are:

Question Parts

( a )

Calculate the average period (in seconds) for each length.

( b )

Using the average periods, calculate the experimental value of the acceleration due to gravity (g) for each length. Use the formula T = 2π√(L/g). Show all steps.

( c )

Comment on the reliability of the experimental values of g obtained. Identify two possible sources of error and suggest how they could be minimised.
