Objective
Establishing the formula for the oscillation period of a
mathematical pendulum.

Principle
A mass of small extent, which oscillates in a light thread is
a good approximation of a so-called mathematical
pendulum. (Ideally, it is a point mass in a rigid, massless
string with frictionless suspension - in vacuum.)
In order to check the formula for the oscillation period,
the different parameters are varied – both some that are
part of the formula, and others that should not have any
influence. The two weights included have the same shape
but different mass. The pendulum length and the amplitude
of the oscillation can also be varied.
