    A simple pendulum is an arrangement, wherein an inelastic thin string of ideally no mass with a heavy point bob at one end and tied to a fixed horizontal rod, hanging freely and is free to make movement about mean point.

    The precautions while measuring period of oscillations:

    Record time for arround 20 oscillations. And record the time for a repeated number of 20 oscillations and find the average period of oscillations.

    The length of the pendulum should take into account hook, sring length, and radius of the bob.

    The sring should not be streched  too much while measuring its length.

    The amplitudes should be very small, or the angle of the amplitude should be very small.
