2018 WAEC PHYSICS PRECAUTIONS TO TAKE NOTE OFF | WASSCE SPECIMEN

A SIMPLE PENDULUM

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.
