Repeat the experience of the discovery of young Galileo, Check: whether the duration of one full vibration of a load suspended on a thread depends on the length of the thread, whether this duration depends on the range of oscillations; weight of cargo; the size of the cargo? By changing the length of the thread, make sure that the period of oscillation of the pendulum is equal to one second, and you will get the simplest stopwatch. At home, you can make a pendulum by fixing the thread in the upper clean of the doorway (for example, with tape).

The period of oscillation of a mathematical pendulum depends on the length of the thread; the oscillation period does not depend on the swing range, load weight, load size.
