About This Product
Students set the length from the pivot to the centre of the bob, starting at 40 cm, pull it aside by less than 10° and time 20 complete oscillations to find one period. Repeating at 60 cm, 80 cm and 100 cm, and plotting period against length, shows how the period of a simple pendulum depends on length and gives a value for the acceleration due to gravity.
Frequently Asked Questions
Why is the swing kept under 10° on the Pendulum of Varying Length Apparatus STEM Lab?
Small swings keep the motion close to simple harmonic, so the measured period fits the simple pendulum relationship; the protractor at the hub helps set the angle.
