What forces act during the movement of a mathematical pendulum? What should be the thread and the weight suspended from it so that the pendulum can be considered mathematical?

The mathematical pendulum will be in the case when the load is suspended on a thread, the length of which is much greater than the size of the load, and the mass is less. That is, the thread should be long, strong, inextensible and not heavy. The pendulum is influenced by gravity. The duration of the oscillations will depend on the length of the thread.
