The students have investigated the influence of spring constant
and mass on the oscillation period and while doing so have learned
the methods required for the investigation of oscillating systems.
They should now apply this knowledge usefully to a thread
pendulum whose oscillation period is influenced by the pendulum
length and the acceleration of gravity.
After having made a number of measurements they should conclude
from this experiment that the mass has no influence on the
oscillation period and, given the proportionality factor, set up
the oscillation equation from the graph of
